Captain Fantastic (2016)

A school-bus journey brings a fiercely self-contained family into contact with people who do not share its father's rules. The movement matters because it lets the children test an inherited view of the world against other ways of living. Viggo Mortensen makes the father's conviction both attractive and troubling. Choose it for a trip that changes the questions a family can ask, with suicide and bereavement at its centre, rather than a simple endorsement of escaping society.
