Dark Knight Returns and Batman Beyond had serious extenuating circumstances as to 'why' he quit. Either a Robin died or he broke his moral code, or something that forcefully broke his will. 'Stopped all Crime' should never be on the list of reasons he quit... and if something DOES stop him from wearing the costume... then he becomes an angry bitter drunk because a huge part of his life's purpose is missing. Retiring with a woman in France or wherever just wasn't right. Batman isn't the happy go lucky 'happily ever after' type of character. Giving him THAT kind of arc is missing the core 'Batman Character' than anything that Burton or even Shcumaker did with their interpretations.
But he shouldn't ever achieve it. He may say he wants it. He may try to get it... but in the end, Crime is NEVER stopped. and there is always some random purse snatcher out on the street who's going to gun down some other child's family in front of his eyes.
And frankly I believe he absolutely DID train with the intent of punching purse snatchers until he dies in the street some night. He's a mega billionaire. If he wants to change the world through politics and social change... he HAS that power and always had. The fact that he had determined the police couldn't do the job and he needed to dress as a bat says that political change wouldn't have done it.
But honestly... what kind of arc is that? What other movie has someone work really to protect innocents and sacrifice their own happiness for the betterment of others... and then just say "Screw it" the cops have it from here. Time for me to do me..." I just can't picture Spider-man or Superman or anyone else actually landing there... except maybe Wolverine. I could picture that... This ranks right up there with Jonathon Kent telling a young Clark "you need to protect your identity... you should have let a bus load of kids die!"
Not even mentioning that 1) he set Blake up as the 'new' Batman indicating that he believed they still needed a Batman.... and 2) Blake did not have 10 years of super ninja training so he's inevitably dead in a week. Batman should be about the man in the gear... not just the gear. No Robin, no training, just toss him the keys to the batcave and go have a margarita....
This is the story that Nolan wanted to tell... but this thread is about the changes to the character and how a director nailed it or how he missed the mark. Batman Begins was pretty good, Dark Knight hit pretty more than it missed, but Rises missed the mark a lot.
Nicholson's Joker and Ledger's Joker are both legitimate takes on the Joker that you can grab comics off the shelf and say "HERE is the Joker they are playing." Rises' Batman is Nolan's own original thing and isn't any recognizable version of Batman.
