The original 1972 tagline for John Waters's Pink Flamingos hyped the film as "An Exercise in Poor Taste." In fact, Pink Flamingos is the Olympics of poor taste. This stunningly perverse camp classicâin which a family of Baltimore lowlifes vie for the title of "Filthiest People Alive"âis packed with brilliant acting (by Divine), terrible acting (by everyone else), and something to horrify everyone.
