Critics Consensus

Masterfully using negative space and unsettling audio to build its creeping dread, undertone erupts as a diabolically immersive aural nightmare.

Read Critics Reviews

Audience Says

Despite an original premise and an effective unsettling atmosphere undertone delivers a somewhat muted horror experience that may appeal to fans of slow-burn, moody fare.

7/10

It's a really solid horror film and an impressive debut, but "Undertone" will likely go the way of "Skinamarink," where some people hate it and others swear by it.

It's extremely effective.

3/5

It’s the writer-director Ian Tuason’s ingenious use of negative space that makes his low-budget debut a standout.

54/100

A film that got lucky with its distributor because there’s really nothing to see here, or I guess in this case, hear.

"Undertone" is an exercise in the "less is more" mantra in horror filmmaking.

The final act devolves into conventional poltergeist shenanigans that feel far too messy, leaving the symbolism-heavy, somewhat open ending a bit unearned.

This one caught me off guard. Super low key one woman show that brought me to tears in the final moments. Did not expect that. If you're a fan of the original Blair Witch it's similar in execution. A slow burn that leaves you feeling haunted.
