Its pretty sh*tty how the top review prevented me from reading this fic for a while until I decided to just read it. I don't regret spending my time on this fic, so far there are only around 20 chapters and everything is fine.
Mc is 'cursed', when he is in his humanoid form he becomes lustful and greedy, that doesn't really matter much though, it doesn't effect him much, as the effects are reduced when he becomes his original skelly form. Off the top of my head there is no grammar issues, the text is easily understandable.
About the r18 not bad at all, right now there is only like a chapter or 2, but then again that is understandable as the mc has just only started to embrace his lustful side, along with his declaration of making every women in overlord his own...
Tbh, i have no clue why author tagged the 1.5 star review, he should just delete the shitty reviews, they are very misleading, but then again i doubt author gives a sh*t on whether the fic gets more reads or not.
But anyway highly recommended, much better than the fics rated higher than this.
