The experience of watching this movie is intensely satisfying. I found myself immediately invested in Lo Blacklock’s impossible situation—trapped on a vessel with people who refuse to acknowledge the crime she witnessed. Keira Knightley delivers a commanding, raw performance that anchors the mystery beautifully. The sleek, isolated setting of the superyacht is stunningly captured by the cinematographer, making the luxurious environment feel utterly sinister. The story maintains a propulsive pace, constantly ratcheting up the tension and paranoia without ever slowing its momentum. Every interaction is layered with suspicion, and the twists are genuinely shocking. The execution successfully translates the book’s claustrophobic suspense to the screen, creating a stylish and gripping ride that is a triumph of the genre. The supporting cast members, particularly Guy Pearce and Hannah Waddingham, perfectly embody the chilling, insulated world of the super-rich, adding layers of menace to every scene. The production design and musical score work in tandem to heighten the escalating sense of dread, delivering pure, unadulterated thrills.
Who Should Watch This?
Stream it if you enjoy intense, locked-room mysteries and psychological thrillers set against glamorous backdrops, relying on strong acting and escalating paranoia to drive the suspense.
