This was the best cartoon/CGI/kid's-movie I've seen in a long time.
I liked this movie a lot. Much better than almost every other 'kids' movie. I don't know why people would give it a bad review; must be because they read the book and the movie wasn't the same or something. Me, never reading the book....I thought the movie was great.
Another theory why some might not like it is because it's an intelligent movie that adults can enjoy. Most kid's movies have obnoxious slapstick jokes every 5 seconds. This movie did not. I even read a negative review that said the jokes took too long to set up. But that's precisely why I enjoyed the movie.
