This is really a history of Sam Wagstaff and his role in the history of photo collecting. As such, it's pretty interesting. Robert Mapplethorpe is in it only as part of Wagstaff's life story. It presents a variety of perspectives on Wagstaff's contributions as well as on Mapplethorpe's motivations. Basically, 'brilliant' to 'junk', and 'true love' to 'gold-digger'. If you're looking for gossip, as opposed to art history, not the film to watch.
