I ever sat through in a theater. Borrowing elements from The Witch, The Conjuring and Paranormal Activity to name just a few, Hereditary is excruciatingly slow, and obvious from the start. The film is largely limited to 2 settings: a modern rustic home where no one ever bothers to turn on a light, and a classroom complete with a teacher droning in the background and disinterested teenagers. There are no supporting characters, save for one, of any note or consequence. The acting is one-note and grating, and Gabriel Byrne's character is annoyingly and unbelievably feckless. What it all means is never explained, and the ending comes as a relief. Judy Collins singing Both Sides Now during the credits provokes snarky laughter; the feeling the whole film is just a big joke.
