Re: Someone please explain why....
I actually don't believe Bruce quit. It makes more sense to me that he simply decided to kill the Bruce Wayne playboy persona, and just live his life privately as Batman with some changes. Him showing up at the cafe is just to make a point to Alfred that he was alive and got the girl; like a boss. Blake is just a recruit/temporary replacement, similar to when Dick Grayson takes the mantle of Batman sometimes. The whole "we wanted the give the trilogy a definitive ending" angle is crap. This ending is neither better nor inferior to the other movies' in the trilogy. They are all open-ended by design. Begins' ending is excitingly scary, The Dark Knight's is emotional and cryptic, and the The Dark Knight Rises is reassuring and symbolic.
