I was only watching it because my aunt wanted to watch it. I was just sitting there as a casual observer. The Civil War is something I know about a lot more than country music. The Ken Burns documentary on that was very lacking. But I read in a few places people were disturbed he left out so much vital info in the new country documentary, too. Basically, it just looks like no matter what the topic, he just gives a superficial view.
I agree Anita Carter had a superb voice. So clear and so unlike what you usually hear.
