The movie is wonderful, and definitely deserves the big screen. A few people have said that it might not be appropriate for children due to the lack of dialog, but that's bosh. We saw it the other night and there were at least a dozen kids from 4 to teens in the theater, and none of them seemed bored. In fact, everyone sat for the closing animation-over-credits. Peter Gabriel proves himself again.
Disney is fortunate to have picked up Pixar. The preview for the next Disney bomb, "Beverly Hills Chihuahua", got quite negative chatter in the theater.
