Nell Carter as an overweight housekeeper, a devout guardian to 3 teenage white girls and a force not to be reckoned with whenever she dealt with the Chief of Police - Carl Kanisky, pretty well sums up what this 1980s sitcom is about.
I found the show hilarious when I was a kid and faithfully tuned in during the first 2 seasons. Nell Carter was unmatched for laughs - I'd always be belly rolling on the floor in laughter, especially the episode where she stays at her friend Angie's and was enraged over Angie's lovable and talking teddy 'Mr. Bear'.
Nell was good friends with Carl's wife and before Mrs. Kanisky died of cancer and went floating up to the Sitcom Heavens above, made Nell promise to look after the family after her ultimate demise. Nell kept that promise, always going above and beyond the call of duty to make sure the Chief and the girls 'behaved themselves'.
It was no easy task. Grandpa Kanisky was a major treat in upsetting the household with his senile wit and slapstick comedy of errors - the moment when he spilled Nell's partially completed jigsaw puzzle off the table was priceless! There was also the moment when Carl said he wanted to have a father and son 'talk', but grandpa said, "You already have 3 children, Carl. There's nothing left for me to tell you."
That was the Gimme A Break! I loved, but it all changed after season 3 and I quit tuning in after that. The theme song I loved was replaced with another tune, Joey Lawrence (and later his brother) was thrown in as the new cute kid and "Nell Harper" wasn't the same anymore.
She was no longer the self conscious, overweight and frumpy housekeeper I adored, but turned into a sassy, well dressed and (by the help of new writers) a totally different woman.
Things got worse later on when the Chief died, the girls went their separate ways and new characters like 'Addy' came into the picture. The setting was EVEN moved from GlenLawn, California to New York City! The show had the most changes I've ever noticed in a sitcom!
To say Nell Carter had an attitude during the show's run makes perfect sense, considering the show's format underwent major changes by Season 3 and became a 'shadow of it's former self'. Allegations from Rosie O'Donnell about Nell's bad behavior during the final seasons adds to the demise of what it once was.
My recommendation: check out Gimme A Break!, but only the first 2 seasons. It all goes downhill from there by the 3rd.
