Yeah it was fun in the beginning, after all who never thought about being transported to another world where you ate a big hero with swords and magic?
But what the hell, I’m pretty sure there’s more isekai now than other genres/settings. It’s gotten to a point that if I see the tag I just move on.
The anime doesn’t have to be good, it just has to make you interested in the lightnovel, which is where the profits are. With that in mind, the cheaper the anime can be produced the better. This is probably why there are so many shitty isekai and they keep coming.
