Yep it's pretty much over. Add this to brainrot zoomer anime like dandandan and JJK becoming mainstream
Zoomers, normies, and foids ruin everything, once something that used to be enjoyed by a specific audience of dedicated adult men who understood and appreciated it becomes too popular, and a mindless horde of teenagers, normies and women start getting into it and talking about it, it's ruined. This has happened to too many hobbies and media to count.

The worst part is of course the corporation$ who ultimately have the final say in the production of the things in question will then respond to that by dumbing down the material for normies, thus ruining the original thing in question, assuming the original creator(s) are even a part of it at that point, because in some cases you have for example manga where the creator dies or loses control but then more content in the IP is released by new creators who dumb it down for a normie/mainstream audience.
Even something just being adapted can ruin it before it got too big, because it's understood that the audience who would watch a show or movie is different from the original book/serialized comic/manga. A good example would be Death Note. It's beyond the scope of this comment to get too into it, but later I will make a post on the Manga section here about how the anime ruined the ending, and the reasons why, which aren't always properly understood or explained by fans, since most Death Note fans aren't critical enough to the anime and how it distorted the manga. (It isn't just the ending, which is just the most egregious example; concisely, the issue is that it leans into making Light/Kira "the bad guy" more than the manga did, obviously for normies, and that's why they changed the ending as well.
The manga has an epilogue chapter removed from the anime completely where two of the main characters admit the world is worse now that it's reverted to having crime: it's clear it is generally conveying they just killed Light due to the positions they were in; not because it was necessarily the right course of action, because they flat-out say exactly this.)
