I saw it hours ago. Was absolutely blown away. The story is pretty horrible in my honest oppinon, but it works for the type of genre the movie is. Of course, the tech behind the movie is incredible. When I first starting seeing the avatar's in action, it was really something just to see how much emotion and expression is shown through their faces, and how natural the movement is.
The film's artwork and sense of color is incredible as well. You might be shocked by what's going on and all the interesting things to look at on screen at once. Nighttime on Pandora looks just amazing.
Ok, so the story isn't that unique and it doesn't completely grab you, but the superb acting, great cast (Sigourney Weaver ftw), and absolute immersive world made me wishing I could just live among the Navi'.
A great film, not the best I've seen this year. It won't be loved by all the critics and you guys, but this is just my type of film, I loved it.
So short, I pretty much found everything in this movie, absolutely incredible with the exception of the story, which, isn't so horrible that it ruins the movie.
