The 3D Imax version of this film is unforgettable. Even though I got a mild headache and nausea from the 3D viewing, it was worth it. The movie was well-crafted with numerous layers such as some parallels with the Native American story and David and Goliath. There are many themes in the film such as "take care of the earth", "love lasts forever", "greed is wrong", and "all life on a planet is interconnected". This is another film from James Cameron that will live long in people's minds.
