Sleep, directed by Jason Yu, is a gripping South Korean thriller that explores the psychological turmoil of a sleep-deprived mother, Soo-jin, who fears for her family’s safety. The film opens with an unsettling premise: Soo-jin's husband, Hyun-su, exhibits disturbing sleepwalking behaviors that escalate from harmless mutterings to dangerous actions. As Soo-jin grapples with her anxiety and exhaustion, the tension mounts, creating an atmosphere thick with dread. The cinematography skillfully transforms their cozy apartment into a claustrophobic labyrinth, heightening the sense of danger. The performances by Jung Yu-mi and Lee Sun-kyun are particularly noteworthy, as they convincingly portray the unraveling dynamics of their relationship under stress. While the film starts with a blend of humor and suspense, it shifts towards more traditional horror elements in its climax. Despite some narrative missteps, Sleep effectively keeps viewers on edge, making it a compelling watch for fans of the genre

really slow and bad movie. just the "keep rolling" is awful. the ending is "happy"? not horror.

Sleep takes a simple premise and executes it with precision. The concept is engaging from the start, and I found myself thoroughly invested all the way through. It doesn’t try to overcomplicate things, instead relying on tension and atmosphere to deliver an effective, unsettling experience. It may not reinvent the genre, but its simplicity works in its favor, making it a sharp, memorable watch. Rating: 3.5/5 – 80% – Would Recommend

Basic but solid film. I really didn't understand Lee Sun-Kyun's performance though. So all over the place, waiting for him to do something.
