Philip Kaufman’s street-gang drama (1979), set in the early 60s, suggests a Martin Scorsese movie gone soft and cute. It jumps and burbles, but the stylized, threatening mise-en-scene doesn’t support the fey emotions. It all adds up to a symphony of murky motivations, as another social group marches to extinction under Kaufman’s practiced hand (The White Dawn, The Great Northfield Minnesota Raid, Invasion of the Body Snatchers). Kaufman and his wife, Rose, adapted a Richard Price novel; with Ken Wahl and Karen Allen.
