And the whole idea of Bruce sulking and going into hiding for 8 years because of Rachel's death, or because crime was magically wiped out because Harvey Dent was such an "inspiring example", is just absurd as hell and makes just as little sense as it did in TDK. And then he retires at the end again, I guess (Sure, that totally sounds like the Batman of the comics).
I think this sums up my most basic problem with TDKR perfectly-- it missed the very essence of the character of Batman. Sure, it had a costume and a "bat vehicle" and a "not-called-Catwoman-version-of-Catwoman" but it really wasn't a good BATMAN movie. Just watch Batman: The Animated Series and you'll see a MUCH better version of the character. A man who dedicates his entire life to protecting the innocent of Gotham because of his parent's murder does not just "give up" over a girl with whom he shared a single kiss and a hand-hold.
Nope. Sorry... don't buy it.
I won't even go into all of the other HUGE logical holes in the film but it is, IMHO, the WEAKEST of Nolan's films. He was closest in Batman Begins-- and even then he was only about 60% of the way there.
