This movie featured computer-generated graphics to tell a story about the possible extinction of some dinosaurs thanks to killer meteors. And, while the story rarely gets much deeper or memorable than that, the animation quality is so amazingly great that this could be forgiven. I'm sure that even by now people might see the movie and think the animation is good, but that is all. Well, when it came out in 2000, it was absolutely state of the art and had critics and the public talking. Sure, movies like Toy Story had already been out, but here was a non-cartoony film done by computer that looked essentially like real dinosaurs running about and having adventures. An amazing technical achievement.
