Emma Thompson is very good in this role.
The production is tight and the cast is supreb.
The subject matter...made me aware of how we all want to age, until we do. How we long for what lies ahead until it's here; then we pine for what is behind us. Both are true in this movie along with something else, that's knowing, it doesn't matter where the journey takes you, it only matters who is holding your hand at the end. At the end Nancy learned so did Leo, that they were only part of each other's journey, not each other's the destination. See it while you're young, but appreciate it when you are old enough to now the difference.
