Sam Did Both Him and Fran a Favor (Major Spoiler)
Major Spoiler Alert
We always seem to rejoice in Sam coming to his senses at the end and leaving Fran for Mary Astor's character. I know I did since Sam was a really good guy who deserved someone who truly loved him and the fact that Fran had been awful to him throughout the movie. However, upon watching it again last week it dawned on me how horribly unhappy Fran must have been for a number of years even before their trip to Europe. Their life in a small town was suffocating to her and she wanted a totally different life before she was too old to enjoy it. Had she and Sam reunited after all she would have returned to that very same life that was boring her to distraction. Sam is too much of a gentleman not to provide very well for Fran financially in the divorce settlement and she can be able to return to Europe permanently and seek the life that she wants. Still relatively young and quite attractive she will be able to attract men and marry if she so chooses. In the movie she entranced three men within a short period of time so I hardly think that she is ready to climb in the rocking chair and give up. That is why I feel Sam did both of them a favor giving up on something that was not making either of them happy anymore.
