Oh man. *spoiler, kind of?*
All that excruciating buildup and they don't even give you ONE SONG by the Wu. It just ends. I know there is a complete DVD of the concert, and that this film functions more as a companion piece, but it's still frustrating as hell when Dirty shows up, and they finally hit the stage, and... roll credits. Wakka wakka wakka. I think ending with a posse cut like 'Triumph' could have made this doc far more satisfying.
All in all, though, very well done. The bits with Sage and Supernat were priceless.
