Ben Foster is the best at playing a crazy fuck-up. Usually, his characters are funny and charismatic. Here instead, he's smart and organized. His only fuck-up is that he has the responsibility of being a single dad, while being a veteran suffering from PTSD. Thomasin McKenzie is fantastic. Somehow, he raised the perfect teenage daughter alone. Maybe, too perfect.
The allure of this film is the fascinating portrayal of an individual lifestyle that refuses to participate in society, but still wants to survive, be intelligent and healthy and most of all, be left alone.
