The Ritual

Director: David Bruckner

IMDB: https://www.imdb.com/title/tt5638642

Review: Doesn't fully land its ending but still succeeds in building a strong atmosphere and tone with clear cut characters and creepy ideas.

Watch it if: You want something that doesn't rewrite the book but reads it well.

And if you liked: Severance, The Descent, The Blair Witch Project
