I was already a Kate Winslet fan, but this performance has put her on a very short list of those who I have ever been so moved, so filled with respect and admiration.
From the moment we first meet her skillfully making pies (old school like grandma) we see a woman who inspires respect. Her troubled marriage becomes apparent right off, but it's not the unreasonable, irrational type of modern day failed marriage relationship. They come to a mutual understanding that they are not happy married to each other, recognizing their own faults and personality differences that are not making for a happy marriage. He leaves her for another woman and while shocking to her, Mildred's inner strength gives you the feeling she'll find a way to manage, although at the most challenging time imaginable - depression era California! We watch as Mildred works hard to keep her 2 daughters cared for while trying to keep herself from falling into understandable depression.
I'll leave the rest for when the series finishes, but I have never seen better acting than in this series, and a large part of that is KW. I believe her performance brings this series to a level it would not have achieved without her. Of course I must credit the directing, writing, and the story itself, for all are wonderful. I could not imagine any fan of dramatic film not liking this series.
