I am a pretty big critic of movies. I love them, but I feel many of them in the past decade have under-performed, and do not live up to the hype.
I went in expecting a lot, and for me, this movie delivered. I don't normally like sci-fi, but you cannot help but becoming completely engaged in the world of Pandora, and the cinematography is purely undescribable.
This movie is already legendary IMHO, and continues to intrigue, long after one has left the theater. The 3D technology needs to be seen to be understood.
