I've already seen this movie. It was called "Battle for Terra," got a very low-profile release a few months back, and was better. Same movie, only less pretentious, less padded out, and with more ambiguous morality (aliens clearly imperfect in their own way). Also, where "Battle for Terra" concerned itself more with the theme of using technology wisely, and respecting the rights of other cultures, "Avatar" was just outright Luddite, which seems horribly hypocritical for a MOVIE. Its certainly beautiful, but the 3-D, while better than most, is still migraine-inducing more often than it is cool. If you really want to see it for the visuals, I'd say rent it.
