It's funny, because I think that to certain other cultures, for example the Japanese, Christianity (and other Abrahamic religions) are Lovecraftian horror. Shinto isn't really a religion in the sense you or I know it, it's more of an animistic set of practices related to daily life. The kami are very much real to the Shintoist mind; the big ones, like Amaterasu, don't have much of a direct interest in your life, and the little ones are more like neighbors. You have to pay them their due respect, and they could grant you boons if you made them the right offerings. OK, now tell this person that there is only one all-powerful god who lives in the sky, that he is keeping meticulous track of everything you do, and that he will doom you to eternal torment if you do not meet his threshold for good behavior, or even fail to properly believe in him. (Japanese have a concept of hell, borrowed from Buddhism, but it's much more a place of repaying karmic debt than of eternal suffering. Japanese hell is time-boxed.)

To me there is a reason why when Japanese media invokes Judeo-Christian themes, it's with a sense of grandiosity and terror. Think all of Evangelion. Or how in a JRPG, any time there's a "pope" character, he's the bad guy (or at least the penultimate boss just before God himself).
