It Follows (2014)
This horror film which has been hailed as a modern day horror classic, and received a high rating on Rotten Tomatoes (currently at 96%), is original, no doubt, but could have been a lot better.
Shot in Detroit, the film is about an evil supernatural entity that follows a girl around after a cursed sexual encounter with her boyfriend, who was a victim of this entity and passes it along to her.
I liked it, but hoped I would have loved it.
