I actually enjoyed Avatar very very much, because I simply knew the story itself was not going to be relevant (you know, bad guys vs ecolo good guys) and decided to just watch it with an open mind, and if you stick to the visual acid trip it is, and consider it just a CGI masterpiece, it's awesome. It was also the first movie I watched in 3D, and I really remember being blown away by the aesthetics of the first hour of the movie ! As dumb as it seems, I really felt emotional just because of the depth of the visuals in the first part of the movie ! I sort of passed through the fact that we are more and more difficult to impress with technology, and more or less realized how far we already are in this field.
Reading all your comments, I think I'm gonna adopt the same attitude with this movie
