I think most people watching will assume that [the interview with Bob Dylan] is new, most probably with Scorsese himself asking the questions. Certainly there's nothing to suggest that it isn't. It turns out though, that this interview happened in 2000, and it was conducted by Jeff Rosen, Dylan's manager. ...Now, I haven't watched the whole documentary yet. I've only watched the second half of the first half. But it seemed amazingly old fashioned to me. I'm not surprised it's on PBS. It looks quite PBS-y. And I'll admit to being bored by now with the basic Bob Dylan story -- you know, the one where the climax is that he goes electric and pisses off folksingers. I'd prefer something with a little more edge, like the old documentary "Don't Look Back" or the book "Positively 4th Street" or Dylan's own book "Chronicles." I really detested all the drawn out, reverent material about about the role of folksinging in politics. It just didn't bring out how phony that was for Dylan. The most authentic thing about him is the way he felt like a phony doing that -- as I see it. "Another Side of Bob Dylan" -- I love that album -- that meant the non-phony side, didn't it? ("Ah, but I was much older then. I'm younger than that now.")
It seems strange that Scorsese apparently turned down the opportunity to speak more with Dylan, and instead ran with the old stuff from five years ago. So what exactly did Scorsese do? An (admittedly very beautiful) editing job? But then what did David Tedeschi, the editor, do? Was Scorsese principally just a name to use as ammunition in persuading people to surrender their archive material?
I'll watch the whole thing and come back and admit it if I think this preliminary view is wrong. Feel free to argue with me in the comments.
