I was 9 years old in 1981 when this show debuted. Though I watched Gimme a Break from the start, it goes without saying that I lacked the maturity at that age to fully understand the adult humor and social issues being explored.
As Gimme a Break only enjoyed average ratings at the time, it was not a big candidate for syndication. As a result, it has been decades since I last saw the show.
I caught it again recently on YouTube, and I was pleasantly surprised. It was better than I remembered as a kid, perhaps because I could fully understand everything now. It's funny, charming, well-written, and even manages to tackle some serious issues. Most notably, it holds up surprisingly well today, which can't be said for many of the more popular sitcoms at the time.
The show was also fairly unusual in that its strongest episodes were in the first two years. Most successful shows take some time to find themselves, but Gimme a Break hit its stride early. Sadly, the show started to slip starting from season 3. Nell Harper's increased creative control was part of the problem. She was a very talented actress and singer, but not so much on the creative side. The series really took a nosedive in its final season when the girls left and the setting moved to New York.
Even so, this was a good show, and in fact deserved better ratings when it was on the air. Try watching it again, and I bet you'll enjoy it more the second time around.
