Despite cardboard characters and a predictable plot, this movie succeeds wonderfully on the strength of its beautiful world-making. I want to go to Pandora! Someday films like this will have deep stories and real characters as well as a stunningly realized out-of-body experience. But for now, enjoy the trip, and the many flashes of imagination in the lovely small details of its richly realized alien world. The story and characters are intriguing as far as they go, it's just disappointing that they remain so shallow, as in Disney fare for children. The film has welcome green and anti-imperialist sensibilities, without finding anything new or subtle to say about them. Kids will love it.
