Don't agree that those points about the Joker are a negative though. It makes him almost seem like a force of nature, in the same way as Anton Chigurh in No Country for Old Men for example. I quite like it.
Correct me if wrong, that's not what makes Batman villains so interesting. The status quo is they have some redeeming traits and motivation. Here he's nothing but, like you said, a mindless force of nature to serve another round of reckoning for Gotham (again). This is where TDKR Bane did a whole lot better.I don't understand why this is a bad thing. He's not supposed to be redeeming, he is the complete opposite of Batman.
Loki was treated with far more respect than TDK Joker imho. He was given a solid backstory, given sympathizable motivations, sex-ed up for the female fans, had his machinations fleshed out, even had family and character development, faced the entire Avengers where each member could feasibly take him out solo. You won't see Joker solo-ing the Justice LeagueThe thing that Joker and every other DK villian has had is that you feel like the Joker one upped the Batman a few times before being caught whereas Loki is treated like a joke. A mere annoyance. MCU just doesn't treat their villians with the same level of respect as DC does.
