I'm surprised there's not already a thread for this movie (or is there?).

I went to see it over the weekend and thought it was great! The 3D tech is awesome (IMO), it's certainly come a LONG way from the last 3D movie I watched.

The plot wasn't particularly innovative, but Cameron can certainly tell a good story. I thought the ending was a little hard to swallow
Spoiler:

Earth won't just send more ships and soldiers back to Pandora to get all that unobtanium? Really? I just don't buy it, we'd load up and go back and torch all the nice blue-people and take all their stuff. The Navi should have gotten justice by trying the boss and worked out some kind of deal with Earth for the unobtanium. Maybe we'd let them build casinos on Earth or something

but it is what it is. I think the corporation that was mining the unobtanium should start selling second-lives as Navi instead of the mineral. Imagine the profit as old people from Earth give their life savings to have their minds transferred into nice young Navi bodies!
