I did learn a lot about my man in the '60s and early '70s. I didn't follow his career much after that, so I found this an easy way to catch up, although the DVD does not cover his comeback in 1997. Many talking heads, including various band members, and occasional short interviews from the past provided lots of little details and yet so much was left out too.
The editing could have been tighter to make the 110 minutes less boring; I also didn't like the style of the choppy editing and the lack of a central narrator to fill in and make the transitions smoother and easier to follow. And why must we see the interviewer? Overall, a low budget feel to the production, like his main focus was to have fun with it.
Another disappointment was the lack of any of Dylan's music actually performed by Dylan. There are some detailed reviews on line you can find by doing a Google search, if you're considering a purchase. Nice that our library had a copy to view.
