If you're unfamiliar with the creepypasta format, think of an urban legend told in serial format and often expanded by other storytellers from the audience. The creepypasta with which Boomers are most likely to be familiar is the Slender Man.
Whether the source of the terror is a rubber monster in the woods, a ghost girl who infests smartphones, or a cursed video game, each creepypasta reads like a deracinated rehash of the American remake of an early aughts Japanese horror film.
What's missing is any kind of internal logic for the plot to hang on. We don't even get the cheap anti-drug and fornication morality plays of 80s slasher flicks. The hauntings/curses/murders occur at random because the victims happened to be in the wrong place at the wrong time.
It's also noteworthy that when some kind of background lore is needed to make the spooky threat intelligible, American Indian legend and prefab Wiccan claptrap are the go-to sources. Summoning a priest to conduct a house blessing or an exorcism is as rare as a Republican in Hollywood--whose fare is nonetheless put to shame by most creepypastas. At least the latter are honest efforts at entertainment.
The Millennials had their identities stripped from them and suffered a crisis of meaning which they collectively resolved by giving in. Zoomers are the first Western generation born and raised with no inherited identity and no awareness that there ever was a meaning to it all. The situation is going to get much worse before it gets better.
One reason for the dearth of contemporary Christian horror is the baffling paralysis that's beset most Christian authors. Christian horror shouldn't be a sermon dressed up in genre trappings. It should be a genuinely terrifying story told from a Christian worldview. Those are the best kinds of horror stories, anyway.
