But the atmosphere is toxic and the natives so hostile, the only way to survive is to use an Avatar, which is what our main character Jake Sully chooses, to control the body of one of the Na'vi.
Don't want to give too much out if you haven't seen it, but if you haven't seen it yet, you're f***** up.
The CGI was incredibly well done, making the Pandora creatures beautiful and elegant. The music itself wasn't memorable but listening to the soundtrack itself gives you the emotional feeling of the forest described in the movie.
Great movie, great actors, and its in 3D!
