Independent Brazilian film with amateur actors (acting in a theatrical style), astonishing cinematography and edition, very little dialog, and a symbolic (and somewhat hermetic) story about the life of people living in the margin, portraying the poor, among prostitutes and beggars, near slums and garbage on the margins of Tietê river. It is a quite unique film. It seems that Charlie Chaplin, Roberto Rossellini and Mikhail Kalatozov have been mixed in a cauldron with Brazilian sauce.
