After retiring from a trip that saw a great deal of people dressed in cowls, joker make-up, and capes I am ready to report. You must see The Dark Knight Rises in IMAX. The experience is completely immersive. Given that a majority of the prologue's action takes place in planes at 10,000 feet in the air, you will appreciate the benefit of a larger screen. A few peeks were offered of Catwoman and the Tumbler, but the real treat was seeing Bane in action.
To address the elephant in the room, yes, Bane's voice is a little difficult to decipher at points, but it is synthesized and—I think—meant to emphasize his inhumane nature. Beyond that there is nothing to worry about on the villain front. The Joker may have been a master of psychological warfare, but Bane is all too willing to burn Gotham to the ground. A shot of him dropping Batman's shattered mask to the ground before the prologue ends is all we need to know. This is a monster of an entirely different sort.
