This film is an interesting character study of an inhibited, uptight single mother, her wild sister, and her rebellious, coming-of-age daughter. It didn't earn a higher rating than 7 because some of the scenes and dialogues are cliches, but it's definitely worth a watch for its unconventional African-American middle-class setting. One of the themes is that mothers can learn as much from their daughters as vice versa.
