I've read that it's very good even though it's a "love story". I've seen some black and white footage of Cash's shows. If they captured the energy and the clickity-clack early sound he had with The Tennessee Two, I have to see it. I saw some footage of him doing Orange Blossom Special on PBS. It was early b&w. Sweat was pouring from his face as he played 2 harmonicas at an unbelievable tempo - made me want to get up and boogie!
