The watcher can choose whatever meaning life has from this story. This film is full of wonder. I saw it when I was young (23), and now again at eighty-one years old. Kier Dullea's sensitivity is a reflection of every human fear; Janet Margolin is a reminder in the flesh of how vulnerable women are--and how immortally beautiful as a flower that lives but a single day. Everyone in the movie--the other patients, the psychiatrist and his aid, the mother and father with their son at the train station--is so recognizable in his or her role, extensions of the best we would hope to be, and examples of the worst we too often are.
It's a good movie. For me, it is a great movie.
