This movie could've been unanimously the best in the trilogy if they cut out or shortened some of the dragging story lines and added an extra 30 mins or so to flesh out the underdeveloped arcs and added an extra Batman sequence. I think that would address all the complains about the pacing, dragging middle act, lack of Batman, and underdeveloped characters/stories.
As much as I loved and enjoyed the IMAX, I feel bitter that it could've been the reason why we got so many scenes cut out.
Splitting it to two could've worked as well specially if they wanted to use as much IMAX as possible and as long as they don't use it as an excuse to just further expand the storylines that already took much time in TDKR and dragged it down.
More of these would've worked in a 2 part movie IMO:
- additional Batman sequences
- Developed Tate arc where they show her actually work her way to Bruce's heart to make her betrayal actually mean something to the audience
- Catwoman's origins and definitely more interaction with her and Bruce/Batman to build her relationship with him more
- some flashbacks on what happened to Bruce in those 8 years
- Flesh out Gordon's story arc
- Additional Alfred scenes
- Bruce working on the Wayne legacy/philantrophy
- Longer time in prison to make the long time spent in rehabilitation and retraining actually translate well onscreen
- Show how Bruce got back into Gotham and him working on rallying the troops against Bane
- More Bane
- Explore the class warfare
- Longer 2nd fight between Batman and Bane, maybe even have a 3rd fight
- More, more, more Batman!
A good cut off would be the prison scenes. Either end with Bruce being thrown in prison in the first movie or end it with him making the triumphant climb (depends on whether they want the 1st to end on a low or high note).
I do wonder if the idea of splitting it to two was brought up. I'm sure WB would've been more than fine with that....
