Evolution Boxed Set (2001) Review

Evolution Boxed Set (2001)
Average Reviews:

(More customer reviews)
Everybody knows that when it comes down to the final question in a game of Trivial Pursuit that they should make me try and answer a science question because I know pretty much nothing about science and nature. This is because the one thing I knew about high school biology was that you dissected animals and being sick in front of the smartest girls in school did not appeal to me at all. So I took Life Through the Microscope (it involved drawing) and Ecology (it was the only class that fit my schedule) and missed out on Biology, Chemistry and Physics. However, since I did my dissertation on the infamous Scopes "Monkey" Trial I do have something of an interest in the controversy over evolution if not the concept itself. This seven-part series exploring various facets of evolution was perfect so someone like me who insists on having theory of any sort mixed with a heavy dose of practice.
"Evolution" is as much about the profound impact the evolutionary process has had on our understanding of the world around us as it is on the various versions of the theory that have been expounded in scientific textbooks for the past century. The series basically focuses on five key concepts regarding evolution, sandwiched between episodes that constitute a dramatic introduction and a controversial coda:
"Darwin's Dangerous Idea" offers dramatizations of key moments in Darwin's life along with contemporary talking heads explaining the profound implications of the evolutionary theory and the place it holds in the scientific community today as a pivotal concept. It takes a while to adjust to the episodic approach of the dramatizations, which come and go without a real sense of regularity, but since they dramatized the famous retort of Huxley to Bishop Wilberforce and other key moments in the popularization of evolution there is a certain effectiveness to it all. What you get from this episode is a better idea of what the initial complaints were to evolutionary theory and who was making them.
"Great Transformations" explores the evolutionary changes that caused the incredible diversity of animal life that exists on earth. The focus is on the development of the four-limbed body plan, which is explained in the context of how animal life moved from water to land and eventually to human beings, thereby answering the key question of why are human connected to all life.
"Extinction!" represents the flip side of evolutionary transformations, explaining the how and why behind the fact that 99.9 percent of all species that have ever lived on earth are now extinct. This leads to the provocative question as to whether human beings are going to cause the next mass extinction on the planet.
"The Evolutionary Arms Race" puts the entire concept of natural selection and survival of the fittest in the context of humanity's battles with microorganisms, looking at a case study regarding the reemergence of tuberculosis in Russian prisons. With the alarming spread of resistance among pathogens that cause disease, the episode explains how this particular "race" offers the major threat to human existence. The scary question here is whether we are fighting a battle we cannot win.
"Why Sex?" makes the contention that in evolutionary terms sex is more important than life itself. But on a more pragmatic level is addresses the question of whether males are necessary to perpetuate the species, looking at a wide variety of case studies drawn from nature. This episode also explains the principle of monogamy in evolutionary terms.
"The Mind's Big Bang" addresses the question of why humans are the dominant species on earth. The answer is found in the past, when something happened to primitive humans to trigger a creative, technological, and social explosion, which ultimately allowed humans to dominate the planet. The episode tries to uncover (literally) the primitive forces that contributed to the emergence of the mind of the modern human being.
"What About God?" is the coda to the series in that it returns to the initial question of Darwin's day regarding the conflict between evolution and religion. The debate is presented within the context of a college student whose family is not happy with what he is learning about evolution at Wesleyan College, a group of high school students trying to get their local school board to allow the teaching of creationism, and the activities by adults on both sides of the question to win this pivotal battle. I consider the episode to be remarkably even-handed, but then I do not think there is an inherent conflict between the two, which invalidates my opinion for true believers on both sides.
Overall I like the fact that "Evolution" goes for depth rather than breadth. The case studies, at least to my uneducated mind, come across as being representative of the issue under discussion. The DVD series also features access to the Evolution Web site with its interactive games, activities, and biographies, so those who would like to get additional information and insight on any one of these topics can easily do so. There are also student lessons for teachers who want to work these episodes into their science classes and a printable teacher's guide (remember, "Evolution" was produced by WGBH Boston, which means we are talking--surprise--public television).

Evolution offers a groundbreaking and definitive view of the extraordinary impact the evolutionary process has had on our understanding of the world around us. Beginning with Darwin s revolutionary theory, this seven-part series explores all facets of evolution the changes that spawned the tree of life, the power of sex, how evolution continues to affect us every day, and the perceived conflict between science and religion. Includes:Darwin s Dangerous Idea: Interweaving key moments of drama in Darwin's life with current research, Darwin s Dangerous Idea explores why his theory of evolution might matter even more today than it did in his own time.Great Transformations: From the development of the four-limbed body plan, the journey of animal life from water to land, and the emergence of humans, Great Transformations focuses on the important evolutionary changes that triggered the earth s incredible diversity.Extinction!: Some 99.9 percent of all species that have ever lived on earth are now extinct. Extinction! explores why, then confronts a frightening notion: Are humans causing the next mass extinction the sixth in the history of life on earth?The Evolutionary Arms Race: Survival of the fittest: Is it raw competition, a level of cooperation indispensable to life, or both? Explore our own spiraling arms race with microorganisms the only real threat to our existence and trace the alarming spread of resistance among pathogens that cause disease.Why Sex?: Investigate the endless variety of sexual expression and the powerful hold sex exerts over almost all living things. And discover why, in evolutionary terms, sex is more important than life itself.The Mind s Big Bang: Between 100,000 and 50,000 years ago, something happened that triggered a creative, technological, and social explosion, allowing humans to dominate the planet. What forces may have contributed to the emergence of the modern human mind?What About God?: Of all the species on earth, only humans try to explain who they are and how they came to be. Encounter real human stories of people struggling to find a balance between religion and science, realms that play very different roles in assigning order to the universe and a purpose to life.

The Universe: The Complete Season One (2007) Review

The Universe: The Complete Season One (2007)
Average Reviews:

(More customer reviews)
I am reviewing the Blu-ray version of The Universe Season One.
Let me first frame my review. I am a big astronomy buff. I have been interested and studied astronomy all my life. Although I dabled in aerospace engineering in college due to my love of space, I ultimately changed my major and have never really worked in the field. In fact I don't own a telescope. Most of my interest has been satisfied by books and wonderful TV shows like Cosmos and The Planets.
So, to me this series would have been perfect fit. A modern Cosmos with all the latest technology, computer graphics, and newest imagery. However, this series is dissapointing. I wanted this to be the outer space equivalent of the stunning Planet Earth series (or even walking with Dinosaurs), which it is not. It's not that it's horrible or even bad, just it left so much on the table.
So, I will outline what I find as flaws and then finish the review with the positives.
1) It's a little to cutesy. The narative style is a little too casual and relies on a lot of comparisons that are a little trite. For instance, they describe how Jupiter flings comets and asteriods out of their normal orbit (which protects the inner planets) by comparing it to a frisbee thower. So we have a lady on a field throwing a frisbee over and over. There are descriptions like, "I want to go ice fishing on Europa" from professional scientists, and using pool tables to make analogies of particles in the Sun colliding, but doing it over and over, or how the threats to the Earth are like an amusement park (except that they aren't at all!!!). Most of us get the point with the mere mention and don't need the extended display of terrestrial footage. It comes off as dumb and slightly insulting. Especially since most of the analogies are weak at best and very misleading at worse since they don't quite work. The narative comes off as trying to be hip and plays to a younger or naive crowd.
2) Animation quality is inconsistent. The computer animations can be quite good, but many are also quite bad. It's inconsistent. In fact some are high def and some are standard def or even blurry! That's unexceptable for computer animations. Even if rendered at lower rez they should be clear. My only guess is they couldn't get the originals. For instance on the rocket launch of the Mar rover missions the picture quality is very bad. However, I have Roving Mars on blu-ray and know it's quality is top notch. Why didn't they get the source? Some animations are really hokey too, like 10 years ago. Still some animations are quite good.
3) Constantly repeating a few graphics multiple times throughout the show. This one is really annoying and kills any desire to revist the show for another viewing. They constantly replay the same few computer animations throughout the episode too many times. This combined with the repeating of the people/earth shots, screams to me: We only had so much budget and we are stretching it as far as we can.
4) Lack of real images. It's amazing that we have soooo many good high rez images of many of the space topics they cover and they choose not to use them. Hubble has put out some great images as well as many other satellites. There are 1000's of photo's of Jupiter and the moons, Saturn, etc... and yet we get very few. When we do get some they are usually blurry low resolution and only shown for a few seconds (see mars episode). This would have been a great way to fill space and show the awe of the universe without repeating the same canned footage and computer animations over and over.
5) Lack of historical context or mission data. The show seems to find a couple things it focuses on in an episode and then avoids a lot of other stuff. for instance, when discussing Jupiter they show only one probe that visited, Voyager, but not a single mention of any other mission. There's no context into what we found out and when. No grander understanding to the journey of exploration and what it has uncovered over time. DOn't get me wrong, I don't want to see another show about how engineers built a satellite at NASA. But knowing that many other probes visited and what they found and how their data got better and answered questions from previous ones....
6) Misleading computer graphics. This one is probably my biggest beef with the show. In and attempt to dramaticize the show, much of the images are flat out misleading or wrong. For instance one animation has the moon (as in Earth's moon) revolving around Jupiter. Another has Europa in front of a star field that is zooming (like a ship going into hyperspace). Or when they show a Gamma burst from a star hitting Earth it looks like a huge glowing space ray. Or showing the asteroid field as heavily populated sea of rocks like a sci fi movie (I had to tell my wife, the asteriods are so far away from eachother that you wouldn't see another one if standing on one). These are plain turn offs if you ask me. It doesn't give the right imagery to those that don't know any better.
7) Formula of 4 or 5 concepts. It seems that each episode has at most 4 or five concepts it touches upon and no more. You can start to see and predict how the episodes will go and realize they aren't going to go in depth on a particular episode since they spend a lot of time on only the four or five areas. For instance, Jupiter they talk about How it Formed, the weather patterns, Europa, and Magnetosphere. There is so much more they could have gone over when discussing Jupiter and the moons.
I could go on. I had high hopes for the series but feel it's a pop culture cable television show with little BBC or PBS feel to it.
So is it good at all? Well, yes, it's still decent. This does fill a void in space documentaries. There are a few new nuggets of information that I am gleaning and some of the animations are still cool. If I were an average person without any knowledge of space, I might find it really neat. It might inspire some children to take up astronomy. Some episodes were more interesting than others (like the one on our Sun).
All in all, I give it a recomendation if you are curious. THere aren't that many astronomy documentaries and even Cosmos and The Planets are pretty dated. If you can get past the narrative and other flaws then you will probably find it was worth it.
I think if you have high def cable/satellite though, I would just watch it on TV as it airs. You probably won't find the need to buy it.
UPDATE: I hadn't viewed the bonus feature "The Big Bang" prior to my reivew. I have to say it was MUCH better quality than the regular episodes. It actually showed the history of astronomy including early scientists and theories of the universe but from a unique perspective. It showed only those people/theories connected to the eventual big bang theory. That was nicely done. It put a good wrapper around the whole big bang theory. Also the special was high def throughout the entire program (only rarely did this special drop in lower def material). So the consistency of the high def production was apparent. Even old phots were given the high def treatment and look excellent on screen even if they were only black and white. The show was a little light on CG. I could have enjoyed some more attention to dark matter and it's role in the universe's evolution. They also only showed one theory for the end of the universe, the Big RIP. They didn't cover the convergence or other theories. I guess the show is about the big bang and not the end. All in all, this bonus feature adds quality to the package. I would have given an extra half star to make my review 3 1/2 stars because of it.

Adam (2009) Review

Adam (2009)
Average Reviews:

(More customer reviews)
I cried during a lot of this movie....my young son has Asperger Disorder, and this is the most accurate depiction of a person on the Autism Spectrum that I've ever seen. I cried tears of joy that someone finally "got it," and will make others aware of the challenges and gifts of persons affected by Asperger's. I cried because I know my son's life will be more difficult due to his Asperger's. I cried because the world will present obstacles to him that I will not always be there to help him with. I cried because when we left the theater, my son was staring thoughtfully and I asked him to share his thoughts and he said...."Wow, I didn't realize that I would still have Asperger's when I grow up." I hope this movie brings awareness of autism to a large audience, and people will open themselves to getting to know a person with the disability....to become friends....and to realize the beautiful treasure that having a friend on the autism spectrum is. Too many people with Asperger's are lonely, ignored, unemployed, rejected, teased, and bullied. I hope this movie helps to change that in a small or big way, for my son and others....This is a lovely movie - it's funny, romantic, hopeful, and a great love story - you will never forget it.

When We Left Earth - The NASA Missions (Limited Edition) (2008) Review

When We Left Earth - The NASA Missions (Limited Edition) (2008)
Average Reviews:

(More customer reviews)
Here's why I like this set:

The image quality is (mostly - see below) very good. Even with the 16mm film source the extra resolution of Blu-Ray is apparent and some of the film is staggeringly effective. As has been stated in another review, the modern interviews are pristine.
The variety and scope of the clips is excellent. The makers have sourced every possible movie from private hands (cine films) and NASA and there's a great deal I've not seen despite 40 years of interest in the subject.
The narration is well written and appropriate. This feels like a story with narrative rather than a straightforward documentary.
Here's why I dislike this set and think it's a wasted opportunity:
Despite the quality of the film clips there are some that have clear and very obvious visible and not just minor anomalies but persistent great big black blobs in the same place on the screen. This 'dirt' persists across clips taken at varied times, even months apart and in very different locations, so it wasn't on the original film. That means, logically, that it's a projection fault and that it wasn't spotted during the HD transfer to Blu-Ray. that's VERY disappointing.
More importantly there's the issue of the music. I'm British and (until recently) our TV documentaries used the original audio soundtrack alone rather than additional music. If music was used then it was sparingly and appropriate and it certainly didn't get in the way of the original audio. During this presentation the music is near permanent. It never stops except for a few seconds here and there. It drowns out narration and more importantly it all but removes the original audio. Subtitles are provided for capcom recordings (voices to and from the spacecraft) but they wouldn't be needed if the infernal music would just shut up! Not only that but the music isn't of good quality and is stupidly over-blown, false drama in every moment. The scenes are dramatic enough, leave them alone please. In the extras there are standalone clips of the astronauts training (etc) and I though at least with these there'd be the original audio but no, the music is even worse and there's NO original audio at all. Shameful. I realize that this is the norm for American TV documentaries (Nothing personal, you make the best TV in the world on the whole) but it ruins the experience and should be resisted.
So, a very very good set partially spoiled by the music and some transfer anomalies. If you can cope with the music then don't let the anomalies put you off. It's probably the best NASA footage on Blu-Ray so far but it could have been the best full stop.

Hi I first saw one or part of one of Louie's DVD/CDs online on YouTube my sister sent me the link or told me about it. It really blew me away I was so WoWed by his Talks I have now seen all 4 and own them several times over because I have given away several of them and purchased like 20 or more for other people at Church and Campmeeting last year 2008 my personal favorite is How Great is our God! I wish everone could see this and just realize how Big our God is and how really Small we reall are. The Lord God wants us to know him and to really get to know him you have to have an experence of True Genuine Salvation. Louie tries to wow you to get you to look beyond your little problems and see that there is a God outthere that although he's bigger that anyone can even imagine yet he's small enough to live inside your heart. To have a Passion for Christ you must see his passion to realize how much God loves you he sent his only begotten Son Jesus to die on a cruel Cross the Cross of Calvary to purchase our redemption so you and I could really be Free So if the Son therefore shall make you FREE you shall be Free indeed! Not free to do what ever you want to do but to be free to live for God and give him the Glory honor the praise that he alone diserves he is worthy. Worthy is the lamb that was slain! Worthy is our God of all our praise! Thank you Jesus

Right now, massive meteors and asteroids are orbiting dangerously close to Earth. Some may even be poised to hit us in the foreseeable future! Where are they? What type of damage will they cause? What can we do stop a caroming asteroid thats headed toward us, or prevent future Near Earth Objects from lining us up in their sites.
Episodes:

EARTH: They have left deep scars all over the face of our planet and are responsible for one of the biggest extinctions in history. Scientists believe that its not a question of if theyll strike again, but when.Cosmic Collisions: Earth covers everything there is to know about meteor clashes with our planet and how scientists are preparing for the next deadly assault on Earth.

SOLAR SYSTEM: Our solar system is a cosmic pinball machine. Rock piles as big as cities plow into planets and leave destruction in their wake. Cosmic Collisions: Solar System travels through our cosmic neighborhood as we examine how collisions created our moon, left gashes on Jupiter, and how pieces of Mars ended up in our own backyard.

GALAXIES: Galaxies smash into each other, stars collide with the force of several nuclear bombs and black holes fuse in a deadly fireworks display.Even our own galaxy marches toward a clash with its closest neighbor, Andromeda. Cosmic Galaxies journeys through space as we examine the cosmic battles being waged between celestial bodies.

PREHISTORIC DISASTERS: Since the Earth's creation 4.5 billion years ago, the planet has been struck by a series of catastrophes, each one pushing life to the edge of extinction. But from disaster comes new life - and while the dominant species on the planet were wiped out, hardier creatures survived and thrived, moving into the vacuum left by the extinction. These creatures in turn took over the planet until they themselves fell victim to yet another mass extinction.The Earth's history is rife with prehistoric disasters that have molded the planet and changed the course of evolution.But with each disaster came another leap forward on the evolutionary trail from single celled bacteria to humankind itself.
