I saw TDKR on the *real* IMAX screen in NYC. It felt like the theater was flying in that first scene. I wound up going back to see it again. And it wasn't in 3D!
Locally, we have a LieMAX...but it's a much bigger screen than the others and I love the picture on it, so I don't mind seeing movies there. It's where I saw Man of Steel today.
I saw This is the End last night, which was of course 2D on a regular screen. Almost forgot what those were like.
