Metacritic rated the film as "generally favorable" with a critic score of 78 based on 8 reviews. Benjamin Lee of The Guardian said "Beware the Slenderman is both haunting and poignant, a sad tale of what bullying, untreated mental illness and crushing loneliness can create. It’s pre-empting a fictional horror film about Slenderman, now in production, that seems somewhat irresponsible in comparison." and gave it a 4/5 stars.
