By having its boogeyman be a personification of STD’s that slowly stalks its victims, It Follows is a successful horror movie about Pepé Le Pew. Which is interesting, not only because we need more gritty reboots of Looney Tunes, but because slasher movies have always been about sex as a subtext. By making it the actual primary plot, we now have an alternative method of teaching kids about safe sex. It’s a much more effective method of promoting abstinence than Catholicism.
