While this film's end has some pretty awesome IMAX sequences (and consistently in that ratio, to boot), there are a lot of times where it's just too jumpy from one to the other, especially in the same scene.
The worst example is of...Warning: Spoiler! (Click to show)
Selina Kyle in the bar with Stryver. The conversation before is in 2.39:1, then when she starts fighting, it switches to IMAX. It's not just the aspect ratio that's the problem... the field of view, colors, black levels, and everything else just completely changes. The inconsistency is so vast, it doesn't mesh well at all feeling like it's a part of the same scene.
I've seen that scene twice in a regular theater since the IMAX midnight showing, and unless you know what to look for, it's not as noticeable. I think a consistent 2.40:1 version of this film would take away this issue.
