3. Hereditary

Toni Collette is a natural treasure. And she often does her best work in the horror genre. (Witness her Oscar-nominated performance in M. Night Shyamalan's The Sixth Sense, if you need a reminder.) But be warned, because the madness of Hereditary isn't for everyone. This is the kind of strangeness where you will question the destination of the story every step of the way until every last detail is revealed. Once it all makes sense, the dark journey becomes more clear... and you instantly want to begin a repeat viewing, to start answering puzzling mysteries. We lost our head for Hereditary, and think that you will, too.
