This movie was absolutely amazing. I loved the 3D features, it made you feel like you were in the story. The storyline was great. It was very simple and similar stories have been done before. The only difference was the amazing special effects and James Cameron's special touch to make this movie great. The characters looked real. You could see the resemblance between human and Navi, but with the 3D, they looked real. I think this movie is definitely a must see, but not a movie you'd see over and over and over again in the theaters, as it is pretty long (even though you don't really notice).
