"Francine Joy "Fran" Sheffield (née Fine) is the series' nasal-voiced, big haired protagonist, portrayed by actress Fran Drescher. Her character is bubbly, outgoing, and humorous but also caring and responsible of the kids and her job, and plays the mother figure for them. Fran frequently gets into trouble, but usually solves the problems herself through seemingly ridiculous antics or by relying on her street smarts. In the last season Fran and Maxwell have twins; a boy and a girl named Jonah and Eve. Also in the last episode Fran, Maxwell, Grace, along with Niles, C.C., Sylvia, Morty, Yetta, Val, and Fred move to California."

Yeah I'd say it was meant as a compliment.
