A film that is fun, frightening, and smugly surprising, especially as it strides smoothly into a final beat that will leave you drop-jawed.

As substantial as a communion wafer and marginally more enjoyable than Sunday school, The Cleansing Hour feels torn between a funhouse style sensibility and the pretense of “saying something.”

The Cleansing Hour, a grisly shocker anchored by terrific performances and deadpan humor, adds a modern twist to the possession story and uses the living embodiment of evil to highlight the dangers of social media.

It's admirable just how much the film runs with its concept and takes it through original, and often hysterical, twists and turns.
