Imdb
 PG-13
Overall:  A crippled marine is being dispatched to a moon planet called Pandora. He must control an avatar body and get the aboriginal Avatars to trust him, as he learns their ways, to get the mineral that's worth 20 million akelah. He must face creatures that want to eat him and is torn between following his orders and helping the Avatars which he feels like it's his home too.

There is lots of bad language and some smoking cigarettes.
It looks like the avatars show nudity but it is graphical to where the jewelry covers the parts. Also the marine (in the avatar stage) falls in love with an avatar and they kiss (saying they are mating).
There are some spiritual scenes about a tree of life and a spirit dance.
