Here's a question: in nearly every genre of popular entertainment, "Christian" is a modifier that almost always means a scrappy, smaller project fighting it out for box office success. Limited release, from a studio like Angel. Usually met with "it means well" indifference from believers and mockery from the general public.
But with horror? Suddenly, mainstream audiences are willing to buy it wholesale. "The Exorcist" is the most famous horror movie of all time. It's also straight-up Catholic propaganda. As is the bulk of The Conjuring franchise, one of the biggest box-office success stories of the last 100 years.
Take vampires. A literal inversion of the Christ story, to the letter. The perfect antagonist from a Christian storytelling point of view. Even in popular retelling like Salem's Lot, the framework of the story is that holy water burns 'em, the Crucifix keeps them away, and the Church knows what it's talking about--and is right about everything.
I'm not saying you've gotta love horror. Im not arguing there isn't plenty of schlocky, exploitative crap out there.
I am saying that it might not be the smartest thing for believers to dismiss the single strongest inroad it's got into popular storytelling today.
Good and evil are real. The spiritual world is real. Stories about those things resonate with people for a reason. There's nothing inherently wrong with exploring those realities in the form of story--in fact, I'd argue that we have to.
Never understood the "scary stories bad" crowd. Feels like 2 inches worth of thinking on the subject. "I don't like the way this makes me feel, so it's gotta be wrong."
