"The film is set in the deteriorating cities and countryside of southeastern England—vividly rendered with alarming realism and minimal use of sci-fi futurism—amid geopolitical chaos that has led to a massive refugee crisis, which has in turn led an immigrant-fearing and authoritarian U.K. to close its borders to outsiders who seek its shores. Terrorist attacks in European capitals are just routine items in the news crawl. The world stands on the brink, and no one has any clear idea of what can be done. The film, in hindsight, seems like a documentary about a future that, in 2016, finally arrived."
