I wouldn't watch a 4 hour documentary on just anyone. I can see he had a lot of control over the content because some things were not mentioned. Not that it didn't portray him in a negative light sometimes. Only fair. It was bizarre to me though that the movie didn't mention Dylan until the 2 hour mark. You could hear the influence from the very start.
highly detailed and entertaining; don't be put off by the fact that it goes for almost four hours (I watched the first half one night and the other half another night tho). a must-watch for fans and highly recommended for people who just dig classic bangers. plan on day drinking too much beer and watching this again in the near future.
