Some Isekais are great works of fictions...these tried and failed. Mostly every character is horrible and mean to the MC for no logical reason, and usually the MC and ML are irritating in their own ways (MC is this awesome, smart, strong flashy individual...but does dumb stuff constantly and the ML is an a$$hole with a hot face and a "reason" for being an a-hole). Most are trash, but fun trash.
