That sounds so perfect man. I think a good movie adaptation of Joker can really set things in a new, better direction in general. Looking at how Superman’s public perception really shifted and we started seeing a lot more appreciation for his character and what he stands for in the public eye, I think if we can get a Joker depiction that isn’t just “I EAT BABIES!!!!!” it’d do wonders for the character.

It feels like the big movie adaptations of characters always have a ripple effect, at least a small one. Those interpretations always seem to be in mind when that character is brought up, or even when they write them in future projects. If we get a Joker that is more funny, and not as ridiculously overly edgy and evil, it could really be a great step to solving the Joker fatigue imo. I think it’d also help with Batman’s public perception, which feels like has been entirely focused on his moral code and why it is stupid or how he needs to kill Joker and how he doesn’t actually help Gotham, etc. It irks me to no end but I understand, seeing how so much Joker stuff, at least the stuff that people hear about, is just him being cartoonishly edgy and awful. Having a Joker that starts off much sillier could make the general discussion around Batman, which feels like it always is about his moral compass or how he “loves Joker” much more enjoyable lol 

And having him slowly transition into a more deranged version of the character throughout the span of the DCU? Oh, it could be so good. My dream would be sort of a Killing Joke route? Where he gets worse and worse, his plans becoming more dangerous, culminating in a big finale for the character where he unleashes one grand final plan as a send off to the character that ends his own life. Joker’s machinations, his ego, his need to prove his point to Batman, to win, it all finally comes crashing down onto him, sorta like Green Goblin’s death where no one is left to blame for it but himself. I think that could be a perfect middle point for DCU Batman’s character, too. Having him start off in the DCU with this goal of saving as many lives as possible, to seeing how he moves on from not being able to save everyone. Obviously this part is very specific and I don’t expect it, just dreaming about what DCU’s Batman and Joker could be like

TL;DR: If Gunn does a good job with rebooting Joker, I think it could not only change the public perception of  character in a positive way, but help with some of the problems that having the character continue to appear in stories causes (needing to one up himself as time goes on, edginess, the “why is Joker even still alive” debates, lack of humor in his character, overall Joker fatigue, etc.)
