Michael Cameron has created a world that is graceful, poetic, fierce, and ecologically correct. The transition of his lead character makes perfect sense within the context of the story and the love story. Of course the 3D, the sound, and the overall technical quality were superb. If I have anything negative to say, it is that the final battle was a bit long and repetitive. But again, the effects were so right on that it is but a minor flaw in an otherwise terrific film.
