I saw this last Sunday. We saw it in 2D. I don't know if it was the theater we saw it or what, but there were some scenes that were just a mess of blur, particularly the opening scene with Smaug's attack. I want to see it now in 3D HFR to compare.
I loved the movie, though. The scene that everyone is complaining about didn't bother me. Anyone who follows fantasy knows that dwarves are nearly indestructible. They also had a wizard along that could have done something to soften the blow.
As others have mentioned, it sucks that I have to wait a year for the next one to come out.
