It wasn't the second coming of Nanny & The Professor, only because 1) there was no magic involved, and 2) The Nanny lasted three times as long as the Juliet Mills-Richard Long entry that ran from 1970-2 on ABC.
The plot is laid out rather quickly. Bridal consultant Fran Fine (Fran Drescher, who also served as a producer) gets a double shock when she learns that her prospective fiance, who's also her boss, has been cheating on her, and decides to end their personal and professional relationships at the same time, firing her so that his new squeeze can take Fran's job. Well, he did look like a punk, anyway.
However, the theme song plays before the first commercial break and spoils the rest of the plot. Not a good move, but somehow, they got around it. Anyway, Fran winds up at the home of British millionaire Maxwell Sheffield (Charles Shaughnessy) and is hired on as a housekeeper, tasked to mind her new boss' 3 children.
While Fran Drescher might've had an annoying, nasal voice, it was offset by her hourglass figure. However, it was Daniel Davis (Niles) who stole the show with some of the funnier putdowns. It's too bad he didn't land another series gig after The Nanny ended a six year run in 1999. Drescher has had two series since, neither of which lasted very long, and reruns are airing in a block on weekends on TV Land.
