FINALLY a website that analyzes Avatar the way it should be percieved. Does anyone else get scientifically intrigued by the futuristic possibilities this film presents, or fascinated by the diverse description of an entire ecosystem of Pandora by James Cameron?

"Ultimately, this is a movie that can be enjoyed on many levels; the crusade that the heroes find themselves on, the jaw dropping scenery and computer animation, and exploring a new and richly detailed alien world and culture; as well as puzzling over how certain aspects of the alien biology might or might not work."
