If there's been a Making A Murderer-shaped void in your life since you completed the final episode on Netflix, then listen up: there's a new true-crime show set to grip you to the core.

About to premiere at the SXSW film festival, _Beware the Slenderman has received rave reviews and just like MaM, it has a very big twist affecting the verdict of the case it documents.

The HBO documentary follows the 2014 Slender Man stabbing, which saw two 12-year-old girls charged with attempted homicide for luring their friend into the woods in Wisconsin and proceeding to stab her 19 times.

The victim survived but the brutality and horror of the 2014 crime attracted national headlines - in part because the girls claimed they committed the crime as a sacrifice to fictional ghoul the Slender Man, to protect themselves and their families.

Beware The Slenderman

If you're not familiar with the Slender Man, count yourself lucky. A fictional supernatural villain, he originated as a meme for an online competition in 2009, and was then perpetuated through online folk tales, video games and art. He's depicted as having a tall ungainly figure, is usually featureless and wears a dark suit. Creepy, right?

The documentary follows the lives of the two girls, Morgan Geyser and Anissa Weier, for over 18 months, documenting how and why they committed the crime and delving into how it relates to the morality of modern media and its impact on young minds.

The girls' trial is currently being placed on hold pending an appeals court ruling on whether they should be tried as adults - a conviction that could mean up to 65 years in prison.

HBO will issue a release date for the documentary after it debuts at SXSW in Austin, Texas on 11 March. Get set to be gripped.
