I enjoyed the DKR. I think the task that Nolan has set out to accomplish is daunting, and nigh on impossible. You have to reconcile the ridiculousness of the character with a desire to root the film in realism. With this duality come two sets of people with divergent expectations you need to please. Not an easy thing to do, and he makes a fist of it.
However, despite really liking the film I strangely find myself arguing more with those who also liked it, than those who dismiss and lampoon it. When someone tells me they don't like it I can accept that and understand it perfectly. This is a film about a ninja that wears a fecking cape while fighting crime. Some people are just never gonna be able to swallow that amount of fatuousness, no matter how heightened the realism(for that very reason) is. Others will complain about it not being true to the comic book(e.g. going emo for 8 years). And I'm not a fan of the comics but I can understand this objection as well. So I don't feel the need to aggressively defend it, or quarrel with the moaners at all. I can understand them even if I disagree.
It seems the only people I really don't get are the ones who hold the movie in an even higher regard than myself. The ones who think this a flawless masterpiece beyond reproach or lampooning. 'Best movie ever', you can't NOT like it etc. I mean, that's just batty, and insulting to someone who likes movies, but I guess also, credit to the film and the director in some way that they can generate such crazed devotees.
