Re: "The Dark Knight Rises" Review and Discussion Thread (spoilers)
Ah, I didn't even think about that when the showed it.
One concept that the end introduced, which I think has been used in the comics, is the idea of Batman as a legacy hero. I kind of like the idea that every few years the current Batman would find a worthy successor who would be handed the "keys to the cave" when that person had had enough, and that this could continue on for years or even decades.
