Alas, cult status breeds cult problems. Broomfield is always a player in his own movies, with his diffident arrogance and thrusting boom mike poking its Pinocchio nose into other people's lies, and he is starting to reap what he has sown. The more hip his subjects, the more savvy the quarry, and the story of Biggie and Tupac, the East Coast rappers who walked the talk of their streetlife and ended up like Sonny Corleone at the freeway pay booth, is as hip as it comes.
