Undertone (2025) offers an unusual take on psychological horror, opting to forgo jump scares in favor of disturbing audio cues, explorations of emotional distress, and a pervasive sense of unease. While the movie isn’t without its problems—the plot has some missing pieces, there are questions left unaddressed, and certain things don't quite add up—its inventive approach to sound and deliberate pacing maintain an absorbing level of suspense. It demonstrates that quietness and audio can be frightening in their own right, which makes it a good choice for people who like psychological horror movies that unfold gradually.
