Door Lock is a Korean thriller adapted from Sleep Tight, shifting the narrative to the victim’s perspective and delivering a tense atmosphere despite a slow start and a predictably weak protagonist. While the mystery keeps viewers engaged with clever misdirection, the portrayal of dismissive and judgmental police adds frustration to the story. The film serves as a stark reminder to stay vigilant and protect personal boundaries in an increasingly unsafe world. Read the full review here: (Indonesian version : alunauwie.com)
