Disclaimer: Coming here from all, so I might not be the audience you're looking for.

I don't tend to just browse for new releases that might be neat, but I've noticed this from the outside as well. Just through the stuff I run into under reccomendations on streaming services and sites. There's a ton of anime coming out that's either isekai, harem, power fantasy, or a combination of those themes.

I think there's potential for some really good shows within those areas, but like most media, I feel that you're more likely to find quality by stepping back a bit and waiting to see what holds up over time.

Konosuba is the only decent isekai show, and it would be an even better show if they dropped the in-world video game mechanics.

Harry Potter is isekai. The Wings of Merlin by TA Baron is an isekai. Percy Jackson is an isekai.

The problem isn't the genre. The problem is that the metric became a target for cheapasses with no imagination who want that trend money.

This is the same shit that happens in every form of media when production becomes more accessible. Idiots pick up the fire and run with it.

The only good isekai is Minna Atsumare! Falcom Gakuen.

Joking (mostly) aside, i'm just sick of generic videogame style fantasy settings in anime. It's always the generic four member party with similar character designs and videogame mechanics.

Delicious in Dungeon is an example of one I sort of like for its shtick. The problem is, that seems to be all it has going for it. The dungeon design is terrible. It looks like it's cut straight from an old school first person dungeon crawler, which was the intention. Still looks like shit.

Generic fantasy videogame setting is just lazy shit. I do understand that there is other anime out there, but it's pretty much buried under piles of trash.

I watched the one isekai with the vending machine. I have keep watching if it goes anywhere. Its 6/10, its interesting but not impactful in its storyline. Information was spitting out similar to doctor stone on the type of machines that exist in the world.

A good one that has some good storytelling was Grimgar, Aahes & Illusion. Talk about more realistic approach and pace for just 12 episodes.
