Wut, you kidding?
"A guy that dresses up like a Bat clearly has issues."
"No, *this* is your mask. Your real face is the one that criminals now fear."
"See, to them you're just a freak, like me . . . they'll cast you out."
etc. etc.
This ****ing guy talks to people in a "Bat voice" when, A. they're not around and B. when they know he's Batman. What the **** do you call that? I don't care how his cape functions, the dude puts on a cape, puts on a bat mask, and beats out of the criminals for a reason and catharsis. That ain't normal and this a movie, not real life.
Even when he's out of the suit he does the voice. What do you call that? It's a little more than dedication. This guy saw his parents gunned down, I mean what?
If anything, prior to TDKR Nolan made it ambiguous. Yeah, there's some symbol of hope talk, but you sort of see him really becoming Batman, especially by TDK's end. Bruce's mental health could be ambiguous. It can be whatever the viewer wants. If it's what Rachel saw, than boy, Bruce is Batman . . . forever until the day he dies.
Forgive me if I like seeing a tormented Batman. An unhinged, but good man that's dedicated. A Batman that doesn't quit and turns his anger and pain over the loss of his parents into something positive by stopping criminals and righting wrongs. A Batman who almost crosses the line (like in TDK with beating the Joker or getting satisfaction out of the "immoral" sonar device).
I don't see who couldn't dig a Batman that grapples with his sanity and is a little more complex, mentally ill character but still is a hero. You make it sound like that's a bad thing? Some of the best Batman incarnations aren't straight laced, take the Frank Miller TDKR Batman for example.
I'm sure Nolan and Co. voices and the feature itself is very, very convincing and fulfilling. They usually are, I love hearing what filmmakers have to say. I'm sure I'll love it. But that doesn't mean whatever they say is written in stone or that they're right, or that it's the way to go. It's their vision, period. The reason these things are for entertainment, that's it. While I was mildly entertained, I was ultimately disappointed, didn't like the story and thought it was subpar compared to Begins and TDK.
It's a little documentary for the film's intent. Just because it sounds great and they have a reason for it doesn't mean I'll like it or agree with it. It's all about perception and interpretation. Didn't like the choices, characters or not.
And it's not just Bruce, it's the whole damn movie. So, whatever. You're free to like it, but don't chastise those that don't. I can see what you're seeing, "I get" where they were going, I just don't like it among other things.
