Watch The First Trailer For HBO's Documentary, Beware The Slenderman
If you daaaaaaaaaare.
I still remember the time I first sent my friend Joe Reid a link to a story about Slenderman -- a ghost story made up just for the internet -- and freaked him the FUCK out. He didn't get so obsessed with the character that he stabbed anyone (that I know of), but a pair of Wisconsin pre-teens did, in 2014. HBO's got a documentary about the case, coming soon: here's your first look.
