U.S. release date. I have so many more movies to see it's crazy. But these are 10 I think are definitely worthy of a Top 10 of the year, so we'll see what gets replaced! The order is also extremely loose. I feel these all bouncing around. Every section of 3 feels equal, with Beautiful Boy being the definite number 10.
EDIT: Hereditary was my Number 1 at the time, but since Midsommar has come out, I found that to overtake it's place in my heart (they kind of are the same movie), so it dropped where you see it now. In a way it still is Number 1, I've just seen it too many times, and it's kind of lost it's magic/been approved upon.
