Slender Man (August 24th)
The Premise: Five teenage girls in a small town perform a ritual to summon the Slender Man, a horrifying entity responsible for the disappearance of countless children.
Why You Need to See It: Slender Man is one of the first creepypastas the internet created, and the cult-like fandom that’s resulted from it is something else entirely. It was only a matter of time before we got a movie based on this particular story, although the fact that this one is also loosely based on an actual attempted murder makes it even more noteworthy.
