Mary Richards' neurotic pal returns to Manhattan and her kvetchy family in this spin-off from `The Mary Tyler Moore Show.' The previously dateless Rhoda finally found love and wed (which proved to be a fatal mistake for the series), but Emmy-winner Valerie Harper's portrayal of her heartbreak when her marriage later shattered gave the show a touching emotional core, as did the wonderful Julie Kavner as Rhoda's insecure sister Brenda.
