Amazing live performances captured on film are the reason to see to see this.
The interviews with Janis don't reveal much, and there's no real sense of her history.
Even the stage stuff is shot pretty straightforwardly, but, man-o-man could she sing!
One wonderful thing is that a lot of the numbers are uncut, allowed to go their full length, which, with Janis in concert, could easily be 8 minutes or more. The power, the emotion, the energy, the sexiness, the sweet sense of fun she brought to the stage could only be hinted at on her albums. For those reasons it's more than worth sitting through the slightly homogenized off-stage material.
