I grew up watching "The Dick Van Dyke Show", so I was exposed to the talents of Mary Tyler Moore at a young age. At the time, I perceived that she was lovable, funny, and somewhat innocent. After watching this documentary, I think those descriptors are accurate.
This biopic provides insights into MTM's point of view throughout her career. It also tries to define her place in (mostly) TV history, as society was redefining itself in the 1960s. To that end, the documentary includes numerous quotes from notable feminists of that era, primarily to skewer her Laura Petrie role as a bad influence. This raises a couple of questions.
First, was the "Dick Van Dyke Show"---and its characters----a reflection of the changing times or a cause of change? Probably both, but primarily the former.
Secondly, if the Laura Petrie role is iconic, is it due to MTM or the producers, directors and writers of the show who defined the role and gave it life through the scripts? I can admire MTM as a person and actor without trying to make her a social icon. As we learn from the documentary, the public really knew little about MTM, the woman, at the time.
The film does illustrate how dramatically MTM evolved and became more self-actualized as she dealt with career challenges, personal tragedies, and relationship issues. It is easy to feel sympathy for her, because she always maintained a sense of humor and she always tried to improve, professionally and personally.
This might not be a very objective overview of her life, but it is enjoyable.
