As I watched this I found myself wondering how younger folks react to this movie. My wife and I are in a similar situation, older, retired, and long-time married. Our daily life and conversations are not that different from what is depicted here.
Lesley Manville (early 60s) is Joan and Liam Neeson (late 60s) is her husband Tom. As the movie begins they are on one of their walks, her short legs must move almost twice as fast as his. After they cross the bridge and get to a certain tree they turn around and head back. About 12 months later the movie ends the very same way.
In between Joan discovers a lump in one of her breasts and this starts a series of doctor visits, hospital visits, treatments, and making unexpected new friends. The movie examines the relationship between the long-time married couple, their devotion to each other, their working together to get past this big speed bump in life.
This is a good movie, we enjoyed it at home on DVD from our public library. Romantic attraction is usually what gets a couple together but ordinary love is what keeps them together.
