It's a very different approach to the character and I guess you either love or hate it. But from the context of Nolan's Batman, the ending to TDKR was very fitting.
The "real" batman never intended to do it forever either.
In the context of Nolan's batman, the director just had to exercise his utter power and actually retire a hero within the context of his trilogy.
