But I wish it would! Now that I think about, I'm pretty happy about how Nolan ended his Batman series. Batman, older and somewhat weaker, fights one last villain, then he retires. People age, and I wouldn't mind comic movies addressing that more.
I didn't like that ending for Batman because the whole retiring thing doesn't seem like something he'd do. People can say what they want about Frank Miller, but the end of The Dark Knight Returns, where he fakes his death and essentially buries Bruce Wayne to live as only Batman feels more honest to the character than the movie's reversal of that.
As a general concept, though, I did like Nolan's willingness to go that route and would love to see it taken with other characters that it makes sense for. And characters where it doesn't make sense? Let them die and not come back (within the same continuity; eventual reboots are fine).
Makes more movies like Days of Future Past and I'm happy. Didn't expect much and it ended up being one of the most fun flicks this summer.
Eh, I'm in the minority that enjoyed DOFP less than ASM2, though I did think it was good. I'd probably rank it just below X2 and just above First Class. Even when Fox makes good movies, though (which I'd only give to the those three), it always feels like they don't know what they're doing and just kind of stumbled upon something that worked in spite of themselves.
