Curator Review

Verdict

A lean, audio-driven paranormal horror with a strong hook and some genuinely unnerving stretches, but it sounds like the film’s execution is uneven and occasionally too familiar. If you like patient, sound-design-forward horror and can forgive a few rough edges, it’s worth a look.

Best for

  • viewers who enjoy slow-burn supernatural horror
  • fans of audio-centric or podcast-set thrillers
  • people who like atmospheric scares over gore
  • audiences drawn to modern indie horror with a minimalist setup

Skip if

  • you want tightly polished plotting
  • you’re impatient with slow pacing and repetitive investigation scenes
  • you dislike horror built around sound cues and offscreen menace
  • you prefer bigger set pieces or more overtly original premises

Overview

Undertone works best as a headphone horror movie: the premise is simple, but the film leans hard into sound, silence, and the dread of hearing something you shouldn’t. That gives it a clean, contemporary hook, and the podcast setting is a smart way to turn ordinary listening into a source of menace. When it locks into its rhythm, it can be genuinely unsettling.

Worth noting

The downside is that the concept can feel a little too familiar in the broad strokes, and the investigation structure may test patience if you’re not already on board with slow-burn supernatural horror. Some of the appeal seems to come from tone and execution rather than narrative surprise, which makes the highs dependent on whether the atmosphere lands for you.

Bottom line

For horror fans, though, there’s enough here to justify the ride. It sounds like the kind of movie that starts off almost casual, then quietly turns meaner and more disturbing as it goes, with sound design doing a lot of the heavy lifting. If you want a compact, modern ghost story with a strong sensory identity, this is in the conversation.
