So, I finally gave The Batman a complete watch through, keeping an open mind...and I liked it a good deal. Its far from perfect, it is definitely too long and having literally 90% of the dialog, in every situation, be whispered is legitimately frustrating. "Riddler", aka Rip Off Jigsaw, is also not great, and there are probably too many kind of pointless subplots that lead to the bloated runtime and pacing issues.
But the actual Batman stuff might be the best Batman in live action, from the action to him actually feeling like Batman and even doing detective stuff. I'm not as sold on Pattinson's Bruce Wayne, but his Batman was great and I loved the end of the movie, where he realizes what he needs to be and we see Batman basically be accepted by Gotham, which is not something I ever expected to get from this movie. I expected them to keep the more "Even normal people hate/fear him" thing like the Nolan trilogy preferred, but The Batman at least seems to set up a status quo of Batman being, while still a scary vigilante, also actively something of a hopeful presence, which I don't think we've really gotten outside of the more silly kind of "deputized crimefighter" thing from the 60s show and the Schumaker films (the Burton films frequently had people distrust Batman, more like the Nolan films but in a more weird Burton way).
This really made me think about the Snyderverse stuff and how, while I don't necessarily dislike him as Batman in theory, I almost never felt like Affleck was Batman. Maybe a bit in the theatrical cut of Justice League and in The Flash film, where he was a bit less of a bad knockoff of Frank Miller's angry old Batman, but overall much like most of the Snyderverse characters I just never felt like I was really watching Batman when he was around, he wasn't even that convincing as a Frank Miller Batman (not that a Frank Miller Batman is something I want to see in live action, but it was obviously what Snyder was going for).
Thinking about it, almost all the other Batman actors only really do Batman or Bruce Wayne well, rarely both. Bale was a good Bruce but a terrible Batman, Pattinson is a great Batman but not much of a Bruce (so far), and I guess I'd say that Kilmer and Clooney were tolerable but not great Bruces and bad Batmen. I honestly think that Michael Keaton probably is the best (serious) live action Batman actor to do both Batman and Bruce Wayne well, although even he is held back by the writing in his movies not really caring about either character, especially in Batman Returns.
Anyway I have ended up liking The Batman film despite its flaws, I probably like it better then the Nolan films (which seemed more ashamed of being Batman films, and had a lot less Batman in them then The Batman does). I do think that Batman (1989) is a better film, its definitely got better pacing and a better villain, but I think you could argue that The Batman is a better Batman film, although I expect the Batman that James Gunn is planning for his universe will be a version I like even more assuming it gets made.
