I've seen the movie yesterday and I don't remember nothing in it suggesting a new religion...
In my opinion, this movie is like a game of the 7 differences. Look at Pandora, look at the earth... Then ask yourself: What's on Pandora that is not on Earth? What's on Earth that's not on Pandora?
Very simple, isn't it? And quite depressing if you're not centered enough...
In addition to this I felt very excited and amazed after watching the movie. And I still feel this way! Felt hangry with humans in the movie from the middle to the end but when it ended I have a wonderful feeling.
On the other hand I don't think the purpose of the movie is awaken people anyway. I think it only pretended to be a sci-fi western. Have you noticed the similarities with native american people or I'm the only one?
