Long story short: It suffers from the Rising of the Shield Hero problem where when you take a step back and look at the MC's actions objectively you realize they're actually a pretty terrible person; but no one in-universe seems to want to call them out on it meaningfully and the MC doesn't seem to want to reflect on it meaningfully, so the show kind of sits in this gray morale sludge, unwilling to ever fully opt-in or opt-out and commit to any kind of redemption arc/villain arc for the MC, instead trying to have its wish fulfillment cake and eat it too.
Just as Naofumi is a slaver: except it's """fine""" because his slaves actually love him and willingly agreed to be enslaved by him. Rou is a kidnapper and a rapist: except it's """fine""" because they're treated well and actually chill with living in a cave and not being allowed to leave and think he's hot anyways.
The other big problem is that the MC just gets fed a continuous stream of OP powers to auto-win any situation he's put into. So pretty par for the course.
Is it watchable? Yeah, I guess.... at least if you're not bored easily. But don't expect anything other than the same bullshit you've seen 10 times already.
