Yes, the plot is thin and derrivitive, but this movie creates a whole new vocabulary in the visual experience you have at the movies. Characters as imaginative as Star Wars, in a world never before seen but fully realized. Don't go for the plot, go for the experience. The animation is so real you start wondering how they did the stunts. Go. Go Go. See it on the biggest screen you can find. Pay the extra money, it's worth 10 mediocre movies.
