I am not a sci-fi fan, but after hearing raves about Avatar I decided to give it a try.
Awesome graphics! You must see it in IMAX 3D, or at least 3D. It's not a movie you want to rent and watch at home unless you have a home theatre system. Although the theme of the movie is sad (Bad Earthlings!), the story line will touch your sense of what is wrong with how we are treating our planet and what our generations to come my have to live with in the future.
