Creep
I’d never even heard of this film until today and I’m very glad I did! It’s very simple and low budget in terms of location, actors, camera work and sound design but it very much makes it work perfectly. It’s instantly intriguing, the building of tension is a constant and gradual build throughout, never dropping the ball even right at the end, which is absolutely horrifying - a perfect reveal. Probably one of the best endings I’ve seen in a while. 100% worth the watch
