That’s kinda what I mean as far as suspension of disbelief is, concerned: billions would fix any city unless you aren’t trying to fix anything and no matter how smart you are you won’t stand up to someone with actual superpowers without a metric ton of plot armor. Like a kryptonian, someone with the speed force or even just magic could vaporize batman with barely any effort.
Like the comics and other media where batman is up against just normal humans I can understand though still not my favourites but the ones where he’s against actual superpowers you usually get some bullshittery.
I’m no expert in comics by a long shot but that’s just been my impression when I did read some batman. The one where batman was actually a patient in arkham and all the villains were just doctors, guards and patients was my favourite though.
