An enigmatic and involving sci-fi thriller in which a father (Michael Shannon) snatches his son (Jaeden Lieberher) from the fundamentalist cult that regards him as its prophet.

They take flight down the backroads of Texas, pursued by both the cult and the FBI, which is interested in the strange powers the boy appears to possess. Joel Edgerton, as Shannon’s doggedly loyal friend, Kirsten Dunst, as the boy’s mum, and Adam Driver, as a sympathetic analyst, are also caught up in the goings-on.

Things do her very weird, but what grounds the movie – and makes it so involving and gripping – is the fervent bond between father and son and the vivid acting.
