a "tired and weary" Batman is essentially what we got in TDKR.
do you think there's a chance they are planning on keeping the Nolan films in this new continuity, albeit with a recast Batman?
I hope not. but, that thought crossed my mind when I read the tired and weary quote.
Fair comment, but the key with the upcoming iteration of Batman is age.
It's a lot easier to be fanatical when you're young, but age certainly starts
to drag one down a bit, Batfleck being 45, and let me tell you, after 40 things start to slow down a bit - not just in a physical sense, but your
beliefs about life in general don't seem so absolute.
When you hit your 40's it's like the days ahead may be less than the days behind (or in Batman's case, significantly less, given how dangerous his
life is), doubts start to creep in, "have I wasted my life ? have I made a difference ? " stuff like that, it probably starts to put cracks in BAtman's idealism. It's also much easier to be cynical as you get older, and cynicism
is what I'd expect to characterize Batfleck's interpretation.
So a slightly older and weary BAtman is a possibility that works. Bale's Batman was scarred by particular events (and particular injuries, reflecting Nolan's attempt to make it as realistic, as possible - remembering that realistic doesn't mean real)
Superman's idealism is a little different, considering he might be functionally immortal, there's always the promise of a better tomorrow. Not so for Bats.
I think it would be neat to see Supes learn a few things from BAts, maybe not become as cynical but get a more realistic view of the human race. At the same time, maybe Supes will rekindle some of Batman's hope and Bats
will see Supes as someone who can carry on the work of making the world a better place after he's gone (after all, Batman on his own is about protecting Gotham, but the JL is about protecting the world in general).
Hopefully, the DKR references were only suggestive of conflict, and they don't actually try and use Miller's DKR as source material - we've already had the retired Batman thing in TDKR, but also, DKR is about Bats and Supes relationship after decades of philosophical difference (which is why it works).
So, bring on a tired and world weary BAtman, but let's see him a little more hopeful at the end of the film.
peace.
