While I'm impressed that Konosuba doesn't take itself seriously and is actually an entertaining comedy without falling to usual harem anime tropes (most of the time anyway), the one thing about it that does bother me is the setting.
It's so painfully generic fantasy. I understand that that's pretty much the point of the show, to make fun of those kinds of stories with similar settings, but it still remains the world the characters live in and thus they always bring up the same things I've heard in other generic fantasy shows so many times.
Here's the guilds, here's the big castle, here's the jobs and classes, here's the monsters in the big-open field, put all your points into this to level up that, etc. It all feels so unimaginative and boring.
Look, I'm not asking people to make the next Middle-Earth, but would it really be too much to ask to put somewhat of a spin on these fantasy settings? Just a little?
But yeah, other than that I'm surprised that the show is actually slightly better than average LN self-insert fantasy trash. Slightly.
