The Last Thing Mary Saw (2021)

The Last Thing Mary Saw is the kind of period horror that doesn’t just dress up in candlelight and corsets—it uses them to tighten a vise around you, turning a small house and a cold winter into a pressure cooker of dread. Edoardo Vitaletti’s eye for 1840s detail makes every creaking floorboard and whispered prayer feel lived-in, while Stefanie Scott and Isabelle Fuhrman give performances that burn with defiance and bruised tenderness beneath a regime of sanctimony. The film’s thrills come less from cheap shocks than from mounting tension and the sickening certainty that cruelty can be a family tradition, all framed through an interrogation that keeps you leaning forward. It’s not for viewers who want fast-paced scares or easy catharsis, but if you like your horror intimate, atmospheric, and emotionally sharp, this one lingers like a bad dream you can’t shake.

The Last Thing Mary Saw is clearly aiming for a bleak, period-gothic nightmare about repression, forbidden love, and the way cruelty can masquerade as faith. The problem is it often feels more like a grim mood piece than a gripping thriller, with slow pacing and limited momentum that can make the build-up feel longer than the payoff is worth. It also seems unsure whether it wants to be a supernatural horror film, a psychological drama, or a revenge story, so the scares and the emotional beats don’t always land with the force they’re reaching for. If you like austere, wintry atmospheres, harsh family dynamics, and a committed central relationship, there’s something to admire here—but if you’re looking for genuinely scary horror or a sharply satisfying climax, this may test your patience.
