This excellent film poses some important questions. For instance, is the young man experiencing paranoid delusions, or is he in tune with the premonitions of a forthcoming apocalyptic event? Those of us who appreciate science fiction films, will be aware how often that kind of question is posed.To me, some fundamental questions are raised in the film:What’s really going in the world?What are the threats that we face?How should we define these?What should we do about them?
