First off, Roger Corman produced it, and pretty much anything with his name on it is guaranteed to be a flaming turd. Horrible, horrible special effects, acting that makes Paris Hilton look downright Shakespearean, and an ending that makes no sense. It's not just a bad ending because it was a cheap, deus ex machina way to wrap things up, but the last shot is a pathetic attempt to be "deep" and "meaningful." You don't shovel shlocky B movie dino-explotation drivel at us for an hour and a half, then get all art film on us at the end, like you've written a horrible research paper for school but thinking that sticking a poem about the subject at the end will get you an A+.
"How is it that hardly any major religion has looked at science and concluded, 'This is better than we thought! The Universe is much bigger than our prophets said, grander, more subtle, more elegant. God must be even greater than we dreamed'? Instead they say, 'No, no, no! My god is a little god, and I want him to stay that way.'" - Carl Sagan
"To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection." - Henri Poincaré
