Art is good, voice acting is good, world setting has potential, but as far as I got there wasn't much of a story, and it all felt shallow. The protagonist is an overpowered Gary Stu character, but that isn't my biggest issue. My biggest issue is this: I don't know what age the protagonist, Bell Cranel, is supposed to be, but mentally he is a child. And if I were to describe this anime with one word it would be 'childish'.
I only got to episode 7, so maybe it gets better, but so many scenes made me think "Am I supposed to think this is cute?" And I didn't.
Every time a character didn't tell the protagonist what they think just because the harem effect needed to be kept up, I was annoyed. Every time the protagonist made things worse through childish awkwardness, I was annoyed. Every time a female character inexplicably fell in love with him, I was annoyed. Is every woman in this world a pedophile? Harsh, perhaps, but while a childish person might make you feel affection, you certainly shouldn't be getting wet, so I can't really find another word for all these women. Basically, most of them fall in love with him just because he helps them, so I suppose this might be self insert for so-called 'nice guys'. This is not a good thing.
Characters other than the protagonist are basically divided into women and opponents, and the latter category get little screen time. The women are all pretty much one dimensional tropes. I think the first woman you encounter, Hestia, is the one you are supposed to "root for", or whatever, but she is absolutely horrendous, and no sane man would stay in her company. Of course, our protagonist is so sexually frustrated that only his childish ignorance keeps him from being an absolute monster, and has the patience of a saint or three, so he's fine with putting up with a bunch of crazy crap for the sake of tits. Not that he knows what to do with them.
I could go on at length, but I have wasted enough time on this rather poor anime. If what I have already said is not enough to discourage you from watching it, then go ahead, but I cannot say I hope you like it, because I would not really want to think that of anyone.
