I'm gonna go against every other comment here and say this is actually good. The criticism of the art for conveying action poorly is completely on point, but with how little actual action there is I don't think it matters much. It looks fine otherwise and the goofy faces the characters often make adds some charm. Also the complaints about the character getting a horrendously OP ability and doing nothing with it feel a bit misplaced, because that's the MC having a huge skill issue. You know, a character flaw, something good characters have, and it makes for a more interesting story when he isn't rolling along easy street the way you'd expect from the premise.
For sure this is a dumb power fantasy, but it rarely feels like it's just sucking the MC off the way a lot of isekai power fantasies do, the characters have at least a little personality, and there's some actual intrigue and plot slowly building in the background. It's nothing special, but it's a good time, and I'd say is being underrated. I've seen stuff rated in the mid to upper 8s with notably less going for them than this. If you have high standards for your isekai it's not going to meet them, but I don't see how anyone with high standards would still be reading isekai at this point when 95% of series won't meet them.
