I totally feel you on the Bruce Wayne stuff. One of the reasons BB sold me was just how strong Bale was inside and outside of the suit. I get what Reeves is trying to setup for the sequel, but if Pattinson had more to do outside of his great portrayal of Batman; I feel like it might have legitimately topped BB.
As for the lack of wits between Batman and Riddler.....yeah I can get behind that critique. Oddly enough, I think there was twice as much of that between Batman and Joker in the deleted scene than there was between him and Riddler in the film, lol. I think that's where the criticism of the film falling apart after the brilliant and riveting first two acts come from. The cat and mouse game between Batman and Riddler kind of gets pushed to the side for all the Falcone stuff.
I think it's clear that this version of the Riddler was conceived of because it checks a lot of boxes:
-Gives us a Zodiac/Se7en style serial killer to drive this noir detective take
-The use of riddles and cyphers actually becomes a very engaging way to start revealing all this exposition and backstory on Gotham's corruption
-Some social commentary with his followers and tying that to the impact Batman is having
-Just the fact that Riddler is an iconic Bat-villain who has never been given the 'dark and serious' treatment on film
Eventually that corruption angle has to go somewhere that impacts Bruce. I don't think Reeves' top priority was making this about the cat/mouse of Batman ultimately catching and stopping the Riddler. Cause we are intentionally denied any sense satisfaction in that regard.
But yeah, once it gets to that point-- the movie is juggling a lot, between tying in Selina's backstory with Falcone, Bruce and the Waynes' backstory with Falcone, before pivoting into a third act that becomes more of a superhero film.
I think it's an admirable and ambitious swing in a lot of ways, but similar to how BvS (and I'm NOT comparing this to BvS) kind of underdelivers on the whole "Batman vs Superman" thing and tries to subvert that, I think this movie kind of does something similar with the traditional Batman vs. villain dynamic. Which I don't a problem with on paper-- but yeah, it can you leave you feeling like there's an itch that hasn't been scratched, especially after 3 hours of movie.
