Honestly, the isekai genre and the related fantasy/kicked out of the hero's party genre aren't any more reductive or generic than most/any other genre out there. There's a ton of generic and bland romantic comedies out there. Ditto with fantasy, sci-fi, superhero stories, romance, horror, sports, dystopian YA, etc. I mean, just think of how many superheroes there are out there who are rich men who went off to the Orient to gain mystic or secret knowledge/martial arts and who returned to their city (and privilege) to fight crime. I can think of a dozen off the top of my head. But occasionally you come across true gems.
This isn't one of them, but it's entertaining enough, with a bit of a variety in that it treats dungeon raiding as a pro sport.
