I felt compelled to throw in my two cents as the review on the main page seems to miss the point. Listen, this movie may not be for everyone, but it is a quality piece of eerie mystery filmmaking. Fans of Ari Aster (Hereditary & especially Sommerset) or Robert Eggers (The Witch, The Lighthouse) will like this film. It is documentary-style and they create a great world where you feel that there's something just under the surface that is a little off. Check it out, but if you're in the mood for a slasher or a more in-your-face horror movie, maybe it's not for you.
