Great acting by Ethan Hawke, but especially by Sarah Snook, who has to juggle a lot of different aspects of her character and she does so effortlessly. The star of the show however, is the plot. This is one of the most unpredictable films i have ever seen, yet what the films story is based of is an age old question, which i will not say, since it is a spoiler. Just watch the film really.
