If Nick Broomfield never found anyone with affection for Courtney Love, it's only because he conspicuously avoided the countless friends, colleagues and fans who appreciate her talent and admire her as a person. But then, why would Broomfield have opened up his film to those of us who work with Courtney and are close to her when there are so many bitter left - behinds and desperate attention - seekers eager to validate his attack on her character? Inquisitors in every age, scared of forceful women, have used all kinds of half - baked testimony to whip up chants of 'Burn the witch!'
