I don't think 3D is entirely useless, it's just not used to its full potential in my mind. Explosions, space battles and what-have-you are nice and all, but when I saw Avatar the one scene that really blew me away was just a bunch of people sitting around and talking, with no camera movement whatsoever. It felt so real and intense.

I want to see some serious drama shot in 3D, I want to see the technology serve story and character.

(And yes, I am anxiously awaiting the local release of Werner Herzog's 3D cave documentary...)
