You leave your own real world and escape into a world of creative imagination - actually believing what you are seeing, and believing anything is possible in the world of other planets and places. The movie possesses every emotion, from love to anger, to anticipation and expectation, to everything possible.
I would recommend this movie to people of all ages. I would not recommend it to younger children - I feel fear rather than entertainment would be a factor.
I predict the movie, Avatar, will be up for several Oscar nominations, and rightfully so.
