This is rather good, an apocalyptic thriller that builds slowly with an ominous edge to the soundtrack and strange events that periodically occur while the characters try to fathom what on earth is happening! Julia Roberts and Ethan Hawke are husband and wife, Amanda and Clay. Cynical and disgruntled with the regimented life of the city she rents a luxury house in the country so they and their two children can get away from it all. The loss of all internet, phone and TV signals combined with a strange event on the local beach baffles them and then two strangers, a father and daughter, claiming to be the house' owners arrive late at night. The story arc is neatly controlled as matters become more and more confusing with the characters struggling to know what to do. There is some great visuals and intriguing twists in the film but there's a deeper study here of the torments in American society. The attitudes to race, wealth and paranoia caused by lies in media and politics are all on offer here. Mahershali Ali costars here as the house owner arriving with his tough minded daughter (Myha'la) and Kevin Baco has a great cameo. Adapted from a bestselling novel this is well worth checking out, a surprising film in a well worn sub genre where it oozes originality.
