This is probably one of the most beautifully animated CG films I've ever seen. The director did a fantastic job at telling this story,which figures since he did Watchmen and 300, and if you've seen those movies you'll see some similarities to those movies in this, such as A LOT of slow-motion, especially during the fights. The cast all did a fantastic job and were all wisely chosen, such as Helen Mirren as the villains wife, Geoffrey Rush as the good, worn down old warrior, now story writer, and the best being Hugo Weaving as the villain (of course) Metal Beak. But the other actors do good jobs as well, Digger and Twilight both being the funniest. The conflict between the main two brothers is very well done and told, and the ending fight between the two is so satisfying to watch.
