Just my two cents, and I apologize for the blocks of text...
I've been reading a lot of reviews after seeing the film, and I've noticed that a majority of the complaints have been about the film not being fun and that Batman not being in the film enough.
Regarding the "fun" aspect. I can understand why people feel this way, but neither BB nor TDK were truly bright, happy films. In TDK, the Joker did bring a kind of insane and perverse lightheartedness to the film, and that was due to the nature of the character. Bane sin't like the Joker, nos should he be. He's there to be an imposing, physical force to counteract Batman's strength. I feel Nolan did a good job making the character stand on his own. No, he's not as calm or collected as Ra's, not as mysterious or enjoyable as The Joker, but there was more than enough backstory and physical presence brought to Bane to make him a decent character.
Many complaints have been that Bane can't hold a candle to the Joker, and my response to this is -- of course he can't. The Joker is the most iconic and popular of Batman's Rogue Gallery, someone who nearly everyone recognizes and feels familiar with. On the other hand, many people don't know who Bane is so it's hard for them to accept him as easily (not to mention you don't see and expressive face and it's hard to understand him in this incarnation). I read a few reviews that mentioned The Joker would have been perfect as the villain again because the whole aspect of mass chaos was in line with what he was trying to accomplish in TDK. I disagree, because the chaos here was more organized and had a definite goal, whereas The Joker's violence in TDK was more random and unstructured. Plus, if Heath Ledger was still with us and he did reprise his role as the main antagonist, I feel like people would be saying "The Joker again?". *coughx-menmagnetocough*
Regarding the lack of Batman presence: yes, I admit there could have been more scenes featuring Bats. For the geek in me though, the first showdown with Bane was amazing fanboy ambrosia appeased my need for Batman in the second half. I understand that won't satisfy the general viewer though (I actually laughed while reading a review stating that the encounter was unnecessarily brutal), but the structure of the story didn't call for too much Batman screen time.
I feel like Nolan's movies were more about the city as the main character, and Batman more as a constructive/destructive force affecting it. The tone of the trilogy, especially of TDKR, reminded me a lot of Gotham Central, where Batman was barely in the story and the officers of the Gotham Police Department were the main characters. Batman showed up only on occasion and was constantly alluded to, and honestly those stories are some of the best "Batman" tales out there (I hear the second half of TDKR draws a lot from the No Man's Land storyline, but I haven't read that yet).
Yes, I understand this does sound like fanboy rant trying to justify some of the flaws in the film. But again, just my two cents.
