Freaky Trailer For HBO's BEWARE THE SLENDER MAN Documentary

If you've been kicking around the internet long enough, you've probably come across tales of the urban legend known as Slender Man, a tall, faceless creature who apparently inspired two twelve-year-old girls to stab their friend and leave her for dead in Wisconsin back in 2014. The girls are now being tried as adults for first degree murder, and HBO has a new documentary called Beware the Slender Man that follows their case. People are hungry for true crime stories right now, and mixing one with a prolific internet urban legend seems like it'll draw some big numbers for HBO.

Beware the Slender Man airs on January 23, 2017.

Shot over 18 months with heartbreaking access to the families of the would-be murderers, the film plunges deep down the rabbit hole of their crime, a Boogeyman and our society’s most impressionable consumers of media. The entrance to the internet can quickly lead us to its dark basement, within just a matter of clicks. How much do we hold children responsible for what they find there?
