I saw this film a week ago and it has taken me that long to fully process my thoughts and feelings. Ultimately, without spoiling anything, the most concise review I can give is that it is an incredible, shocking, daring film about too many things to count. It packs emotional punches unprecedented in our recent move toward safe cinema. By far the best film I've seen in a very long time, and wonderfully feminist.
