I personally like it and think it fits the stories I want to tell.
Also, if done well, it doesn't give me headaches. I am quite susceptible to headaches. So is my mother - in fact, she used to get horrendous migraines from the flicker of film movie projectors and CRT TVs! She much prefers 3D digital projection!
The weird thing is that some people who don't like 3D keep telling us that it's physically impossible for us to like 3D! Um... if I didn't like it, I wouldn't watch it! This is not some kind of weird con act we're playing at. I think that Cameron and Jackson are 100% sincere in their desire to make 3D movies - because they like the medium. And also... from interviews I've read, Nolan did take a look at converting Inception to 3D and liked the results - but he said it would have delayed the release by too much.
Heck, to be honest, when we were working ideas for the 3D cityscape for the teaser (you know, where the city becomes a maze which becomes the word INCEPTION) I remember thinking "wow, this would look awesome in stereo :)"
Oh boy, now the anti-3D camp is really gonna come at me with torches...
