In essence, this is for fans of the album, which are plentiful. Its also a companion product to the remastered album, which has extra tracks, some of which were repolished and reworked.
Even at the reduced price i paid for it from amazon, i believe this could have been so much better than what you get. There's no mistaking the value for money, with 40 or so minutes of additional footage which wasnt in the televised version. However, there is an unmistakable whiff of "padding out" and the great gods themselves being a little careful even after all these years of being a little too open about some of the other things that went down during that period. As a result, it seems to be a little bit of a whitewash/ clean up, which is a bit of a disappointment.
Still, you get a fair number of contributions from everyone involved, including anita pallenberg and bobby keys. The funniest stuff, is via people like bill wyman on the extras interviews, which really seal the deal and make up for the more clinical, overpolished feel of the main documentary.
Overall, it's enjoyable, but not as deep and dirty as the album itself sounds, even to this day.
