I just saw it for the second time, this time in IMAX. I enjoyed it even more this time, and I was able to understand the plot very easily. I think the IMAX sound mix made it easier to understand the dialogue, particularly Bane's. My friend (a sound editor), said that they most likely mixed just for IMAX and then converted for regular theaters, since it would cost a lot to do two mixes. That could be why it's more difficult to understand in a regular theater.
Two things did come to mind this time around. One, why did Blake decide to take the kids out on the bridge when he knew about the tunnel? Was the other side of the tunnel being blockaded too?
And two, how the hell does Bane shave?
