It's some of the most flawless integration of real film and computer animation I've ever seen. Secondly, there are three fantastic sequences in the film. His score was robbed of an Academy Award nomination, but should be remembered fondly by soundtrack aficionados for years to come. I know I catch myself humming it all the time. The other aspect of the film's rating comes from the creative side, and it unfortunately receives a very low rating.
Dinosaur is about as creative as a pile of mud, and only slightly more entertaining.
Amazingly, at least four people are credited with writing Dinosaur in some capacity. The biggest creative pitfall of Dinosaur though is the fact that the dinosaurs talk. Now I know there was no chance in hell Disney would make a movie like this without dialogue, but the film would have been much more effective if it had done without the talking. You understood all the action and emotions in the scene without the need for one single, spoken word. But, Dinosaur is ultimately a family film, and therefore it wasn't written with my sensibilities in mind.
