Just thought I'd chime in here. I saw the film in 3D a couple of days ago, and agree with you Clyde, that the narrative scenes were flat. I took off my glasses several times to see if there was any 3D at all, and would have liked more roundness in the actors' faces and more room volume in the dialogue scenes. I accepted it as the filmmakers' choice to separate the two worlds of Spiderman, but thought they didn't have to dial the 3D that much down. I also noticed that the director or DP obviously were used to compose shots for 2D. Many of the shots had foreground objects placed close to the camera, which would have worked fine in 2D, but unfortunately forced them to reduce the IA to an absolute minimum to make it work in 3D. Interestingly, I found the converted Avengers to have more shots that seemed planned for 3D than the native 3D Spiderman movie that was still using the 2D filmmaking vocabulary.
