I recently watched "The Rise and Fall of The Clash"...not too special in terms of artistic merit, it was basically just informational. I didn't know their manager was a megalomaniac, and that Mick Jones was the booted from the band by Strummer (having been manipulated into it by the manager). And that Strummer later confessed his mistake and tried to get Jones to rejoin the band, but Jones was not interested, having moved on with Big Audio Dynamite. The doc showed Jones in the most positive light, the manager in the worst, and Strummer was made to look a bit naive and a bit of a dick. But it's hard to know what that level of fame and fortune in such a quick flash will do to you.
