Yeah, I’m pretty much on the same page as Superweapon here. I really like 80s and 90s anime, and some 2000s anime can be pretty great too, but it’s hard for me to find an anime from the past 15 years that I can unconditionally enjoy. It’s all either cookie-cutter isekai bullcrap, or insane horniness with massive-titted women. Or both.
In my opinion, “otaku culture” crystallizing into its current, proudly degenerate form is what killed mainstream anime. It has resulted in anime moving further and further away from the interests of normal people, and more and more towards pandering to basement-dwelling masturbation addicts. There are a few shows that are still being made for a well-adjusted audience, but the vast majority is repulsive on a physical level.
