Unflinching documentary of one of the most important figures in the history of popular music. I found it a little hard to watch for a borderline obsessive Clash fan like myself, as the focus was not just on the magic in a bottle that the band found, but rather on Joe, front to back... meaning that there was a lot more to learn about his departure from the 101ers, his attempt to keep the Clash going with Mick and Topper gone, and his time in the wilderness before finally starting to make music again with the Mescaleros.
And, despite the tinge of iconoclasm, Joe still comes out looking great. The mythology is debunked, and the man is raised up, with the result being an exciting portrait whose true beauty is in its style: Julien Temple is a great documentarian, and he lets this story out in just the right way. A winner.
