Death's Sonata is a brutal, unsettling indie horror film that leans heavily into psychological breakdown, religious symbolism, and bursts of shocking violence. It's ambitious and often intense, with some genuinely disturbing sequences-but it's also uneven in spots, and that keeps it from fully hitting the mark.
The story centers on Dr. William Fredrickson, a longtime psychotherapist who starts to suspect that his former patient Charles-diagnosed with schizophrenia-is behind a growing string of violent murders. Charles, now living off-grid in a remote hunting cabin, believes the Grim Reaper is speaking to him directly and ordering him to carry out killings. As the bodies pile up, Fredrickson recruits another patient, Matthew, to help track Charles down before the police get to him.
This isn't a slow, moody horror film. It's aggressive and often relentless. The gore is front and center when it hits, and it's not for the faint of heart-some of the kills are nasty, graphic, and deeply uncomfortable. But they're also grounded in the story, not thrown in for shock value. You really feel like you're watching someone unravel-and drag others down with him.
The performances are solid. Charles is played with a disturbing kind of fragility-he's both victim and threat, which keeps the audience unsettled. Fredrickson brings weight to the role of a man carrying guilt and doubt. Matthew adds unpredictability, though some of his arc feels rushed.
The film's biggest strengths are its commitment to tone and its willingness to go dark-really dark. The violence has consequences, the fear is rooted in psychological collapse, and the religious undertones give it an extra layer of unease. But it's not flawless. Some scenes feel choppy, the dialogue can be stiff, and there are moments where the narrative momentum slips.
