There were times when the 3D was very good and other times when it seemed out of proportion; the interior shots of the lab were bad IMO, it's like they kept the same proportion of distance as they did on the exterior shots, so it seemed out of whack. It was realistic when the ash from the fire was falling. I actually tried to dodge one of the missiles. (We were sitting in the middle of a row that was near the center height of the screen -- darn near optimum)

The CGI was great -- I've never seen better. The Na'vi never seemed "cartoony" or fake and the flora and fauna seemed real, even those great rides. That part of the graphics will take home an Oscar.

I kept my 3D eye-wear cause I'm definitely seeing it again.
