Storytelling at it's finest. The movie hints and then delivers, in unexpected ways. It's not a tale of madness or violence, it's a tale of patterns in society, and allowing things to linger to the point of boiling over. It questions how we engage with others and what that engagement says about ourselves. This movie is not for people who cannot engage multiple concepts at once, those for whom the story as presented is the only story, to be taken at absolute face value. No, it's for those who are capable of reading between lines, interpreting the spaces and pauses, gaps separating moving events and understanding that the moment, isolated, is not the entire event itself.
This film is a masterpiece that is best watched from a viewpoint capable of accepting of things that are uncomfortable in ways both voyeuristic and intrusive.
