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.
Portal fantasy in general is fine( think like inuyasha or digimon as old version of isekai). The issue is the isekai that are just mindlessly cloning each other with some new way to be OP.
