gregwetherall (above) has done an excellent and spot-on job so I'll keep this brief -
as a 15-year rock musician (so I actually get "the wobble bit" - though I'm not quite sure I buy all of it) who grew up with the Rolling Stones, while this isn't anywhere near perfect (likely impossible)
"Crossfire Hurricane" is still very entertaining and a must for any Stones fan. Some of the remixed live tracks are astoundingly preserved and sound great, though imo some of the interview comments need to be tweaked up a bit (though my hearing is shot, so maybe that's me)
Some quick cuts from "Cocksucker Blues" interspersed just at the right moments of some of the live tracks; Keith as usual brutally honest in his comments about drugs, Brian, songwriting, etc - and there's some stuff in Crossfire Hurricane I've never seen before. (no spoilers here) - even Charlie speaks up now & then. The best and worst of Brian is brutally portrayed as well.
All in all, a job well done and definitely worth seeing. I've DVR'd it, seen it twice so far, and likely will watch it again. Play it loud through your sound system.
