Laura Dern is perfect as lanky lass in a small town sparring with her parents, estranged from her older sister, desperate to be liked and to be with boys. Opening moments of this adaptation of Joyce Carol Oates' story "Where Are You Going, Where Have You Been"--with Dern and friends doing the mall--are realistic but nothing too original; second portion of the film, with Laura meeting smooth talking Treat Williams (who comes dressed like the James Dean poster on Dern's wall) is elongated and dry (you can almost feel the director's confidence slipping away). It's an encounter I didn't particularly care for, nor did I buy the rosy ending either. However, there are fine moments in "Smooth Talk", the most devastating of which lies in a conversation between Dern and indifferent sis Elizabeth Berridge (in a terrific performance): Dern recalls a vivid, lovely childhood memory between the two, but after listening and thinking it over, Berridge tells her, "I don't remember..." **1/2 from ****
