Query: boring as hell

I honestly don't know how a film maker could make such a boring piece of dribble with a) the budget, b) the time spent on the film c) three guitarists of this caliber.Anyone hoping for insights on the craft, technique, gear, or anything of depth for that matter might be disappointed. So much of this film was staged or scripted, it barely feels like a documentary.On the other hand if you're the type that can listen to droll guitar playing for an hour and a half, and gets excited seeing stock footage of U2 and Led Zepplin, then this is the film for you.
