Hereditary - 4/5
I managed to avoid all spoilers about this, although as an AV Club reader, I couldn't avoid the major hype they built up. So I came in knowing nothing but that it was ostensibly about loss, there was a weird kid who makes weird sculptures, and that there was a scene that blew AVC's critics away.
Well... I wasn't nearly as enamored as A.A. Dowd was, but I did enjoy it a lot. I thought the movie had major tonal issues and a habit of making me laugh at things that were decidedly not meant to be funny, but I will say that the scene Dowd raved about was indeed shocking as hell and will stick with me for a long time. After that, it sort of becomes an R-rated Insidious, but at least it takes after the good half of Insidious and not the stupid half. To its credit, the cinematography is astounding, and the acting is excellent and deeply uncomfortable for the most part.
Given that this is Ari Aster's first feature film, he did a great job and I want to see more from him. Dude has a talent for unsettling imagery and dread.
