I really enjoyed this movie and have seen it twice (I'd see it a third time, but I believe this is the last week it will be playing. It was a great film for the entire family: I didn't have to worry about inappropriate violence (the food chain is part of nature, so that's okay, and even in this respect the movie was quite tame), and the whole family learned some really interesting things. I was very impressed by the computer graphics, especially the quetzalcoatl. One thing I would have liked to see was a map of what the world looked like at the time, including the location of what is now Patagonia (and my two year old wanted to see T. rex, but he doesn't quite have a grasp on geography). I would love to see more films like this!
