A former teacher (Joel Edgerton) lives deep in the woods with his wife (Carmen Ejogo) and teenaged son (Kelvin Harrison Jr.) while an unseen terror menaces the outside world and people are dying of a contagious disease. When someone (Christopher Abbott) breaks into their house one night seeking water and supplies for his own family 50 miles away, a gesture of kindness has deadly consequences. Written and directed by Trey Edward Shults, there is so much that's good about this movie that I wish I liked it more. Shults does a bang up job of creating a paranoid atmosphere where nothing is certain and trusting another human could be fatal. Shults asks us how far are we willing to go to survive and ultimately, is it worth surviving if we're dehumanized? The women's roles are negligible and the film belongs to Edgerton, Abbott and Harrison who are all excellent. On the downside, I'm getting really tired of movies that are literally dark and this one is always dark, even in its daytime scenes. It's not the kind of film you can easily shake off and I suspect it's a film that will grow on me the more I dwell on it. With Riley Keough and Griffin Robert Faulkner.
