Since Darby's been champion, the Dynamite ratings have decreased each week (617K, 596K, 590K). I'm glad you're enjoying it and it's cool he's gotten this opportunity but "generational run"? How? It's only been a few weeks and hardly anyone is talking about Darby unless you're on the AEW subreddits.
We can all name several examples of silliness in AEW. It's not "for adults." Adam Cole came out dressed as a Ghostbuster and he and MJF hit kids with dodgeballs ala Billy Madison and in that segment black X's were drawn on the eyes of children with their tongues out. Jericho had 'The Learning Tree'. Is a child rubbing his chin for adults? I don't know why you talk up this different version of AEW when the real version is in front of us. You're like Hulk Dragon when it comes to AEW lol. Even in their more 'mature' moments it's silly, like a wrestler running around with his legs on fire, someone filling his mouth with his opponent's blood, and a busty woman's gimmick essentially being "look here viewer, I have large breasts."
It's fine to admit as bad as you believe WWE is, they are a marketing machine and are able to take full advantage of every situation. Fans were wrong about Danhausen and AEW has always been poor at mass marketing. We all know this.
