This movie had a good story and good characters, but GREAT cinematography. The scenery and action were fabulous. It felt like you were right there with them, like you could reach out and touch the plants as well. We also found ourselves forgetting that his avatar was not really him. The story had a good 'hook' as well. We definately suggest paying extra to see the IMAX version, although I'm sure the standard 3-D version is just as good. Well Done James Cameron!
