This 2014 horror flick seemingly came out of nowhere and follows a weird premise: a sexually transmitted curse that kills people. No, it’s not syphilis, and there are probably folks out there who think that this is a pro-abstinence piece, but the uniquely moody tone of the film, great performances, and distinct Detroit imagery make this flick a terrifying flick unlike any other you’ve probably seen.
