I thoroughly enjoyed the two-part Bob Dylan documentary on PBS Monday and Tuesday nights, although it seems odd that all the recent Dylanmania focuses on his first few years when he's had a career lasting more than 40 years. There's a reason for such '60s wallowing, as post-boomer critic David Greenberg points out in a Slate article:
One part of the answer is that Dylan shares a problem with the 1960s as a whole: Scholarship and popular commentary alike are shaped by the baby boomers who lived through the period and have never quite transcended their own youthful enthusiasms.
