Sweetie (1989)

Synopsis
Australian filmmaker Jane Campion directs the darkly humorous family drama Sweetie. Thin and mousy Kay (Karen Colson) works in a factory and lives a dreary existence with her well-meaning boyfriend, Louis (Tom Lycos). One day, her sister Dawn (Genevieve Lemon) arrives with her so-called manager, Bob (Michael Lake). Nicknamed Sweetie, Dawn is everything Kay is not: boisterous, impulsive, and overweight. Kay is consumed with uptight phobias, while Dawn hangs on to her unrealistic childhood dreams of show business. Meanwhile, their parents, Gordon (Jon Darling) and Flo (Dorothy Barry), are involved in a strange separation. Kay, Louis, and Gordon trick Dawn so they can visit Flo at a ranch in the Australian outback. Everyone gets together back at the family home where Dawn pulls an immature stunt, exposing the psychological realities of the situation. ~ Andrea LeVasseur, All Movie Guide
