Undertone

I was excited to see Undertone at a matinee yesterday because it got a lot of buzz at Sundance this year.  I found it to be incredibly unsettling!  Evangeline "Evy" Babig (Nina Kiri), who hosts a popular podcast about paranormal activity with her friend Justin (Adam DiMarco), has moved back into her childhood home to care for her mother (Michele Duquet) who is in the last stages of a terminal illness.  The old house is filled with religious iconography which unnerves Evy because she is an unbeliever.  Justin receives an anonymous email that includes ten audio files of a couple named Jessa (Keana Lyn Bastidas) and Mike (Jeff Yung) as they seemingly become possessed by a demon known for driving mothers to murder their own children.  They decide to record an episode for their podcast using the audio files with Evy as the skeptic and Justin as the believer.  However, as they listen, Evy begins to experience the same phenomena as the couple and she spirals into madness.  Kiri and Duquet are the only actors who appear on screen so most of what happens is depicted through sound.  It is incredibly immersive, and disturbing, because the audience hears what Evy hears and it is easy to believe that the sounds are coming from the house because of the way the dark and empty spaces in the house are filmed.  There were many moments when I thought I saw something lurking in the shadows in response to something I heard.  It is one of the most atmospheric movies I have seen and the escalating dread is unbelievably intense.  What I loved most is that, unlike many recent horror movies, the ending is ambiguous (Evy could be possessed or she could be the victim of her own isolation, grief, and guilt) so the tension painstakingly created in the first two acts is not derailed by a tedious explanation in the third.  See this in a theater with the best sound capability possible!
