As much as I want the Batman movies to leave the Joker alone for about a decade
I’ll see this and raise you “I want Batman movies to leave for at least a decade.” Seriously, at this point I could quite happily go the rest of my life without ever seeing another new Batman movie, animated series, comic book, etc. I don’t think Batman was ever that interesting of a character, and at this point I think anything that could possibly be worth saying about him has already been said, most likely several times over. DC has gone to that well way too many that times. After several attempts, I don’t even try reading DC comics anymore, because I just know at some point someone at DC is going to say “You know what this comic needs? Batman!” and no one’s going to stop them.
