Everything he does makes sense once you realise he literally only makes stuff because he thinks it looks cool. Joker as Jesus is not a deep metaphor, he just looked at it and thought “dude that’s sick”
Apparently he adapted Watchmen (and is going to do the Fountainhead) only because he likes how much sex and murder there is
The Maggie Mae Fish videos on him are great. Dude can only interpret things via Randian Objectivism with a healthy amount of christian savior imagery. And of course putting in as much toxic masculinity as he can get away with.
Also his CGI style may be very aesthetic but it looks like total crap.
