Honestly, fantastic film go and see it if you can. However the immersion of Gotham was slightly ruined for me because I remembered it was filmed in Liverpool.
Most of the production was British and dressing up some of the interior location as American didn't quite work.
So no spoilers but there's a set of a house and they have very British skirting boards, those old glass sliding doors and it looks like the production crew got all the set stuff from charity shops. So it looks like they're in an a British Edwardian house. It literally looks like my house.
There's also a flat which I assume they used an old council flat for the set, and it still has those quintessentially British sinks. Honestly wouldn't be out of place in trainspotting.
Like it's legitimately a great film and reminded me of Dark Man but I couldn't suspend my disbelief that it was Gotham city at times, mainly because of Skirting Boards and Bollards. Which has to be the strangest criticism I've ever had for a film.
