All theatre listings? 3D only (at least where I live) in the 4 different cinemas local, and 6 within the region. I'm not paying £30 to go see a movie.
That's opinion, so will not argue it. However, my opinion is that 3D is just a very gimmicky concept at the moment based on all the other 3D movies that have been released. It shouldn't be forced onto people, certainly not with a major release such as this. Its horribly overpriced too.
I despise post-converted 3D. But Avatar (despite it being shite) and Hugo looked great in 3D so I assume this will too.
