“This seems like an odd suggestion, but Luther is unexpectedly creepy. It stars Idris Elba, who plays a ~not-so-by-the-book~ detective in England. Most of the murders are so creepy I still can’t watch certain episodes alone at night, and I’ve watched the series four or five times. Plus he makes friends with a serial killer because he can’t prove their guilt, and they are creepy AF but very loveable somehow (yes I know how that sounds, you’ll understand if you watch).” —Larsmm
