It has a British "period piece" feel although the period is 1962. Two new college graduates from different backgrounds, which was still a big deal in 1960s England, get married.
She is Saoirse Ronan as Florence Ponting, violinist and leader of a string quartet. He is Billy Howle as Edward Mayhew, much less refined and often confused by his role in the world.
The movie starts with the two of them in their hotel room, about to spend their first night together, figuratively and literally, and much of the backstory is told in a series of flashbacks.
The movie is based on a popular book, and the author also became the scriptwriter for the movie, which is a nice touch. It moves a bit deliberately at times but we found the movie very worthwhile. It plays on a theme that certain moments in life create crossroads and the decisions we make each time can have a great and lasting effect on the rest of our lives.
