Is this really a good dinosaur movie?
Meh. The plot is inconsistent. There are a few fillers (especially the prologue) and some plot holes. The screenplay is not well written. I feel the characters are not developed enough as well.
The voice cast is fine, but not great. Some of the voices don't seem to be as engaging. However, the music in this film is excellent. There is no doubt that the animation is one of the best I have seen. The editing serves the film well.
It's recommended, but definitely one of the worst Pixar films.
