My biggest issue about the Nolan sequels is that they care more to focus on the characters around Batman rather than, well, Batman. Begins is the only one that feels to build around the Bat himself. That's why it's my favorite of the three by a long shot, plus it's score is phenomenal, far better than TDK, and certainly better than Giacchino, who I find very overrated these days.
That's where I feel The Batman succeeded, it was a Batman movie first, though which we literally (at times) explore Gotham though his eyes. It was a step towards the Arkham games on film, which is something that I am baffled hasn't been used as an explicit template for an on screen adaptation yet. It also lays the groundwork for a more complete, dual personality Bruce/Bat; he realized by the end he can do good as Bruce too, something that Bale's version never really does. He just throws money at things.
As it stands, in isolation, Affleck is the only one so far to embody the character with the best sense equity to each side of Bruce. It's such a shame that Snyder took that off the rails so hard with the killing aspect. Those promises of an Affleck film with him more or less trapped in Arkham sounded great. I still think that Affleck x Irons is one of the best interpretations of Bruce and Alfred we've had too.
I do hate that all of them can just take bullets willy nilly though. It's far more exciting see him find ways around firearms than to be a tank. Popping the rifles in the warehouse scene was always a nice touch.
But let's be honest, Batman won't kill you, he'll just saddle you up with crippling medical debt and chronic pain/disability for stealing a KitKat.
