It Follows
I was actually really impressed with it, it was really original and exceedingly creepy, but not super "scary" per say. It's more psychological - It plays head games and builds up a really tense atmosphere. There are some pretty fucked up graphic parts to it, though that will unnerve you. It actually reminds me a lot of the original Halloween; similar shots, lighting and music, and it has this "vintage" vibe to it. Even if you don't necessarily like the horror genre, you should still see this.
