I think it is a great movie. I love Jimmy Stewart and Maureen O'Hara and they play their parts so amazingly well. I was three years old when the movie was filmed and remember it vaguely as a child.
I have always loved visiting the beaches and beach towns. After visiting coastal California several times including the southern San Francisco area, I really grew to love the authenticity of the movie.
I watch this movie at least once a year and enjoy every minute.
