Oh, yes: we can talk

Joan Rivers: A Piece of Work

Crit

Yes, she is that. A brutally honest, or at least brutal, documentary about a very funny and very sad 75-year-old icon. The squirm meter goes to 11 when a heckler with a deaf son takes exception to a Helen Keller joke and Rivers vehemently defends comedy's lack of boundaries ("I mean, 9/11--where would we have been if we couldn't laugh?"), and then it returns there as she grimaces through vicious cosmetic surgery jokes at a Comedy Central roast.
