undertone

The relatively slow burn that is “undertone” culminates in one of the most truly chill-inducing final acts in recent memory.

...builds a continuous amount of dread as it creeps along.

...a myopic and creepy thriller that messes with everything between your headphones.

...doesn’t match its rich promise.

...is the perfect horror film for our era, one in which superstition and technology not only coexist, but feed one another. 

...a nightmarish descent into madness and an impressive feat of storytelling.
