Watching this film today is a real wake up call.  A totally matter of fact look at the varieties of human behavior and interactions, Sunday Bloody Sunday will have you wondering, "What happened?"  The citizens populating the 1971 portrayed in this film posses a reasonable and measured approach to living that we seem to have lost somewhere en route to the twenty-first century.  The screenplay by Penelope Gilliatt is a wonder of simple human being, refreshingly free of the hooks and plot gimmicks that so inundate the cinema of the present.  Schlesinger's direction is an all too rare mastering of naturalism.  A film to savor.
