"Amour" starts out as a grand love story for a refined couple in their 80s in France. They are tender with each other in a way that almost brings tears to our eyes. And their love shuts out others such as their grown daughter who, like most young adults, is rather self-absorbed and shallow. So are her husband and son. The family business is music.
Then the wife Anne has a stroke. Soon after she has another stroke. Those set in motion an almost "Romeo and Juliet" inevitability. We sense that the husband Georges will have to kill her, then himself.
Until that happens he becomes unglued by her suffering and she by watching him take on the burden of caring for her. She had made him promise he wouldn't put her in a hospital.
When it's all over, the daughter returns to roam around the apartment. One is doubtful if she will ever take on the depth her parents had.
