What I don't like:
-The pace at which the story unfolded
-Batman "returns" twice in the same movie
-Missing 3-month time period
-Didn't feel sense of tension
-Batman being out of action for 8 years
I wish I liked this movie more than I do. But after 2 viewings and thinking about and discussing it, I just have some issues with it. First, I wasn't a fan of Batman being out of action for 8 years. That just seems like a lot of time. I would've preferred that he had remained active, but in the shadows and with the police chasing him and such, and for a shorter time period of maybe 2 years or so. One reason I didn't like Batman being "missing" was that his first return to action took some of the wind out of his second return. I would've liked to have seen him come back to action only once, not twice, in the movie. I think it would've made for a more meaningful return near the end of the movie if Batman had been active the whole time, and then Bane breaks him and sends him away, perhaps even broadcasting it to the people of Gotham. Trying to gain their support by taking down Public Enemy #1.
I felt Bane's reign of terror should have begun a bit earlier in the film, and Bruce's imprisonment should've lasted longer (in screen time). Time could've been saved by not building up Batman's first time returning to action, and I would have used this screen time to show parts of those 3 months that were not shown. They could've shown the police living underground and how they made that work. I would've liked some more scenes of Gotham turning upside down. Rich people living on Skid Row, poor people living it up in the mansions and penthouses, crime running rampant with no police around...it would have added to the feeling of terror in Gotham, which I felt was sorely missing. And it would have made Batman's eventual return a bigger deal.
Basically I would've chopped a good portion of the first 45 minutes. Yeah, still have the Dent Act passed and organized crime cleaned up, but Batman still working behind the shadows busting some low-level crooks (maybe show a Calculator-type guy or something) and running from the cops a bit. Then Bane shows up, busts up the Batman, sends him away and takes over Gotham. Then focus more on the terror-related aspects of the film (like they did with the court and the image of people hanging from the bridge). Show Bruce working up his strength to get out of the pit, and then show his "return to action" training.
I felt this movie had so much promise that it failed to deliver on. It tried to be a lot of things when it could have narrowed the focus and come out better for it. Of course this is all my opinion, but it's how I wish they had done things.
