This is a visually beautiful movie bringing the story along in with obvious and subtle references.
The title character is a trapped woman. The 'noblesse oblige'of being the warden's wife coupled with her own frustrations and frailties makes her life intolerable. She loves her children; she hates her life.
Here, she becomes intrigued by a prisoner in her husband's jail. He appeals to her imagination as well as her sensibility as a woman. She finds a soul-mate in their exchanges as she pretends to read-him-to-reform from bible passages. She flees with him and is willing to die with him to keep from returning to her unbearable life.
This is based on a true story. But it is a telling of the story of women, most of whom until the last 25 years or so, had little choice but to marry and to identify themselves in terms of their husbands. Their identity was not their own; their choices had to be appropriate to their marriage station; they were judged by how well they maintained husband's well being and their children's achievements.
While much has changed in women's lives, vestiges of the past still do exist. The references to "baking cookies" in the 2004 presidential campaign signals this.
Mrs. Soffel represents the lives of women over time. She desperately seeks the love and freedom that her standing in life denies her. This has been a common women's theme.
