How to watch Batman?

Hi, I'm currently watching the series Gotham, which more or less shows Batman's past. After this, I'd like to see actual Batman films or series, and I wanted to ask how I can best watch them. I don't feel like watching films from the 20th century. Is there perhaps a Batman film series that shows…

Do these two Joker movies with Joaquin Phoenix have any purpose other than being depressing?

I just watched the second one. Both were just pointlessly depressing. Although I found the second one a bit more enjoyable. The first one was even more horrible. I don't really think the second one is any worse. But overall, both films are a real drag.

Let's be honest, DC really only has 5 good films, namely the Dark Knight trilogy, Joker and The Batman and then one flop after the other. Marvel would be licking its fingers if they had people like Superman, Batman, Joker, Flash, Harley Quinn, Bane, Green Lantern, Wonder Woman etc. and DC just makes crap out…
