The 2007 film The Girl Next Door is a disturbing adaptation of Jack Ketchum鈥檚 novel, which is rooted in the 1965 torture and murder of 16-year-old Sylvia Likens. The film's portrayal of systemic abuse, community complicity, and the betrayal of trust by a caregiver renders it exceptionally challenging for viewers, often surpassing the brutality of the real-life case.
