Under a single label sit films with almost nothing in common: atmospheric dread that shows you almost nothing, the jump-scare film, and explicit gore. Someone who loves one often hates the other. Getting it wrong doesn't give you an average evening, it gives you a ruined one — too much for some, pointless for others.
That's why CUT's "After midnight" mood separates pure horror, the psychological and the mystery. These aren't decorative shades: they're three different experiences. Mystery works through doubt and lets you go home calm. Pure horror makes no such promise.
Seeing the trailer before choosing is more useful here than anywhere else: the grain of the image, the sound, what the film shows or refuses to show all read immediately. It's the only reliable way to know whether a film matches your threshold, and the hour it is.
