I'll only see something in 3D if it's created with 3D in mind. I like the whole experience. If the 3D and the visuals are done well it can carry a bad story (Avatar) and not leave you feeling ripped off or disappointed.
If the 3D is added as an afterthought it sucks. Tron wasn't awful, but it isn't worth seeing in 3D. They don't utilize the technology for about a 3rd of the film, and when they do use it they use it poorly. The way they did the 3d is like looking into a shadow box, when they do use it objects are broken into 3 planes, foreground, midground, background. Things feel more like carboard cutouts rather than true 3 dimentional objects.
I haven't seen a ton of movies in 3d, I don't really care for pixar stuff, but the owl movie was fucking amazing-
The story is a little hokey, but the visuals are fantastic. It's directed by Zack Snyder- the guy who did Watchmen and 300, so he really is a master of the CGI medium. I like that these movies are finally starting to get dark again, think the Secret of Nimh if you were an 80's kid. If you've never seen it it's worth the rental. It's pretty slick even in regular HD.
