It would be better advised if you rent this film from Netflix first before you make your purchase here. As the other reviewers have noted, the transfer from film to DVD can vary, and in this particular case, it was clearly poorly done. It's a terrible shame that this beautiful IMAX film was given such a second-rate transfer.
Normally I would end it here, but as some perceptive readers might have noticed, a vocal creationist has entered our midst, voicing his objections to the theory of evolution being used so matter-of-factly. Now I certainly don't want to belittle Dan, he can certainly believe or disbelieve whatever he wishes. However he went beyond just stating his discomfort with the theory and went out of his way to draw out a couple objections to Evolution, in effect distorted the evidence and philosophical foundations of the theory. Thus, here entails my problem.
Dan complains that the IMAX film, while giving references to evolution, never attempted to provide evidence that evolution had taken place. Is this really surprising? Perhaps Dan should ask himself if just conceivably that the theory might be so well established in modern biology, so well documented in scientific literature, that no rational person questions it today (i.e. such as cell theory, or population genetics), therefore any exposition on "proving" evolution would simply become superfluous. Just an idea Dan.
If Dan is so dissatisfied with the rather simplistic explanations given in the film, perhaps he should actually read some of the evolutionary literature that is readily available (here at Amazon no less). A great text would be Douglas J. Futuyma's _Evolutionary Biology_, or Ridley's _Evolution_, and a few excellent popular works would include Steve Jones' _Darwin's Ghost_, Kenneth Miller's _Finding Darwin's God_, Donald Johanson's _From Lucy to Language_, and anything by Steve Gould or Richard Dawkins.
