Isekai was a thing before the word was popularized and normalized in the west to describe the subgenre of fantasy. I'd argue The Neverending Story is clearly an isekai, for example. And there's been great conventional anime isekais in the past, such as Vision of Escaflowne.
What I'm sick of is the "oh this is like a video game and the NPCs can be manipulated because they're just programs susceptible to cheat codes" gimmick. It's gross and I find it intolerable to follow any "hero" that dehumanizes other characters under any excuse to build a virtual capitalist empire with an infinite harem. It's :epstein: tier :brainworms: to me.
I don't want to automatically reject something I hear about because I hear it's an "isekai" but all too often it means "another video game world with NPCs to exploit!" :capitalist-laugh:
What an empty sort of metagamey victory to fantasize about. How alienating and sad for such "heroes," even if they still deserve :gulag: in general.
chainsaw man is incredible. read the manga, which avoids most of the :awooga: in the anime
it's very much critical of its own horniness, and i think is actually a really cutting critique of the way shitty harem anime (among other things) treat sex and sexuality, and the aforementioned stuff is treated very critically and not for fanservice (in the manga. as mentioned the anime is a little :awooga:)
also: important to note that it is never horny for minors (even once it starts introducing high schoolers) and is only rarely horny for adults
