It's about relatability. Some kinda god ressurrecting me? Straight up fantasy, which I can enjoy as such since it's beyond the uncanny valley. Changing human nature to a degree where multiple romantic partners, family included are okay with you going around knocking up every girl you meet? That's frickin dead center of the uncanny valley for me.Sure, because we can't break a very realistic story setting about a guy who dies and reincarnates into someone's else body.
Also, about incest being unrealistic, that depends on which part of Amer.... the world we're talking about
