why do you think nolan has made this decision to end it after 3 movies?
because he's obviously found a way to end batman's story, and everything after 3 movies would almost definitely be going down hill. quit while you're ahead.
ideally, i would've liked to have seen a batman trilogy filmed back to back like lotr. the main reasoning for this would be so it felt like more of a seamless trilogy. the gotham in bb and tdk seem like they are in slightly different places. then you had the rachel dawes problem. filming a back to back trilogy, you can tell a story over three films, rather than having to tie up the majority of important loose ends in each film like nolan has had to do in both of the previous films. characters like flass, falcone, maroni, two face and scarecrow could've been developed that little bit more if they had written a three film story. i think they planned this with tdk, then made some changes and turned two films worth of content into one. in a sad way, with the untimely death of ledger, it was fortunate that they decided to go this route.
and do you feel you seen everything you could want from nolans batman?
pretty much yes. i want to actually see a true ending, not the batman fights crime forever and rides off into the sunset scenario that the majority want. let's do something that hasn't been done before, just this once.
and how would you feel if they killed batman off?
do i think nolan has got the balls to do it? yes.
do i think he will? no.
would i mind if he did? not if it works within the context of the film.
how do i think it will end? bane will die. bruce will not continue as batman, due to either injury, arrest, death or retirement. in my opinion, josh blake is somehow key to the ending. i'm unsure as to whether he becomes the new commisioner, or even the new batman, but for levitt to be playing such an unknown quantity makes me think his role in this film is pivotal.
