In truth, I'm having a bit of a lark, and of course one major problem is WWE booking over the last, oh, fifteen(?), years. That said, I also think excess and escalation (especially as it pertains to choreography) are issues, sure.
But I'm not totally facetious here. There are genres in this world that get broken by history or developments. I really like ERB's John Carter of Mars pulps, but part of what made them operate was scientific ignorance and what we've learned since prevents new iterations of that sort of Sci Fi. I'm not going to 100% say that it was 100% "hard" sci fi in 1912, but it was driven very much by what the public did not know about science and what they could simply imagine. You could write something similar today but the perception would be so different that you'd almost certain be doing a pastiche or parody or something to be winked at instead of something more earnest and genuine. Most likely, you just wouldn't write something that takes so much for granted and as matter-of-fact. That genre, in its initial form, is impossible and unreachable a hundred years later.
Part of me really thinks that there are primal, necessary elements of pro wrestling that just can't exist anymore in 2019. Wrestling is a medium and not a genre (as we elaborated on at length in the beloved AEW thread) but so much of it is now inward looking and navel-gazing. Some of that is by design (that's WWE for you) and some of it is by the sheer fact that almost anyone who gets into the wrestling business in this day and age is a fan, and increasingly so, a fan of people who themselves were fans. You see it in other mediums/genres as well (you almost can't write a superhero comic that isn't about the entire history of superhero comics right now), but I think wrestling, more so than a lot of other mediums (except for maybe the circus and stage magic?) relied upon a distance between spectator and creator. With that so thoroughly bridged, something innate and primal is broken.
