The story is simple, but theres sooo many details in the enviroment and the special effects are so crazy that it would be too much if the story was any more complicated. After seeing this movie, you are left with a feeling that you have actually been at Pandora.
It was my third time seeing it, and it just keeps getting better. I have seen it in 3D all three times, but only once in IMAX.. and it really made the whole experience of it much better.
