This is a movie about a good marriage about the accumulation of small dramas, never quite reaching a climax, never quite being resolved, that hide within the miracle of a good marriage. Set in Australia in the 1920s, it’s about a family of itinerant sheep drovers. It’s filled with spectacular location photography and has a few suspenseful action sequences, but at its heart are a hundred and one things that don’t go wrong, when they should. The father and mother of a teenage son who make up the family don’t change in the course of the film — they have no “arc”, to use a bit of terminology from modern Hollywood storytelling, which turns characters into geometrical shapes. We just watch scene after scene in which they struggle to remain who they are — two married people deeply in love with each other, deeply committed to each other. We watch the compromises they make, their acts of forgiveness, their miraculous triumphs of sympathy and empathy, their well-worn joy in each other.
