This is the perfect example of isekai trash turn good. Honestly I couldn't get passed the MC stupidness from the manga that I drop on the first chapter. Didn't expect the anime to be this good the MC stupidness is gone. He's not making fun at the guild master hair and laughed like a Ahole, this one is more mature(I think?) because he's not treating this world like a game and realize he must survive in this world.
This one is good because of studio too I think. Take a look at 'Maou-sama Retry' that is one of my top list isekai manga but the animation ruined it. Everything is wrong about the anime one 'Maou-sama Retry' manga is thousand times better than the anime adaptation. It amateur works The MC in the manga is not like the anime one, the anime one looked grumpy asf.
you want a h*ntai protag that has bloated belly wearing a glasses with creepy laughed and breathing heavily when confronted with a girl with the eyes that look at her like he want to defile her when they are alone is that what you want. sorry just kidding.
I just don't want so many bad Isekai anime to come out every season but i think it will stop soon. A few years ago it was animes like chivalry of a failed knight kept coming out. Chivalry of a Failed knight, Sky wizards academy , Absolute duo, Bladedance of elementalers, World break. Not saying they are bad but when the same stuff keeps coming out it feels oversaturated and becomes harder for me to get into it.
I get that. man.. when the next isekai that is actually better than this come out people will judge it as generic because of anime like this came out first even though the better one came out long before this even exist it will be overused like you said.
