Two girls and a guy at a cabin in the woods. One of the girls is a nut job. All the ingredients you need for an Eighties horror fest. Yet this being a product of the school of mumblecore it’s really a talkfest about friendship after Elisabeth Moss’s father has died, her boyfriend has cheated and Katherine Waterston isn’t that close to her any more. Poor Patrick Fugit turns up and Moss is so out of it she doesn’t even remember him from being in the cabin with them same time last year. ‘Auteur’ Alex Ross Perry is the next big thing and this came showered with so many adulatory reviews I was prepared for something special – like Bergman’s Persona. Except Moss’ insanity is clear from the first frame, I like neither actress and given that I can’t even make it through to the end after three attempts I can’t tell you if it ends up with a chainsaw but Dear God I hope it does. Fourth time lucky. The poster is lovely.
