I began watching this documentary with a reasonably strong interest in Lincoln and the remarkable times in which he lived, but I was completely unprepared for the emotional impact of this film. I don't think it's useful or necessary to go into detail about what the film contains in particular, but the story of this family, their struggles, dedication, frustrations, setbacks and triumphs moved me on the deepest level. This is a remarkable story about a handful of extraordinary people and one family, with the huge bonus of revealing a new, and for me, unsung hero. I bought one of her books online before I even finished watching. I want to know Dorothy Kunhardt better, that is certain.
If you can watch this in a detached, analytical way, with a dry eye, you've got me beat.
