Daily Dead writer Heather Wixson scored the film a 3/5 and said that "In terms of creating a creepy and unsettling movie for those who have been enthralled by the Slender Man character over the last few years, White delivers in that department". IGN writer David Griffin gave the film a 6.5/10 and said "If the story behind this chilling internet creation could have matched the quality of those aforementioned strong points, Sony would have a real horror gem on their hands".
