10 Best Under-The-Radar Horror Movies

A true hidden gem from M. Night Shyamalan's résumé, Devil shows him dipping back into his horror roots in 2010 after some failed blockbusters.

Devil is set in a high-rise building, with five strangers stuck in an elevator together, the caveat being one of them is the Devil! It makes for claustrophobic and tense viewing, watching as the inhabitants of the elevator slowly start turning on each other and freaking out when weird things happen. It gets pretty damn grim in that elevator as the cops rush to set them free, all the while discovering that it's not just the five people in the elevator.

Devil is a simple movie, and a fairly short one at 80 minutes, but the budget of a mere $10 million shows that Shyamalan is at his finest when he's under some constraints. It's certainly one of his better movies (although The Visit may be even better again) and it's genuinely unsettling.
