As an 80's child I grew up with all the classic cartoons like Ducktales, Gummi Bears, Thundercats and Ghostbusters then when I was in high school I had the shows like Fresh Prince of Bel Air, Kenan & Kel, Sabrina the Teenage Witch and Sister Sister. Watching these shows was something I used to really look forward to every evening and when they are shown in a rare repeat on TV I love watching and reminising.
Sister Sister had some great episodes. There was something about the mannerisms of the characters which I found just hilarious - I especially remember this of Lisa and Tamera. I remember we were also occasionally treated to the musical talents of Tia, Tamera & Marques Houston (Roger) which I always enjoyed. What was most pivotal about Sister Sister was that despite being a comedy show with the occasional unrealistic scenarios it did address many things teenagers go through and could relate to. The characters seemed like real people and I'm sure I was not the only one to grow up with and love those characters.
I don't know what people expected out of this show but to me like many other similar shows that aired at the same point as Sister Sister they were marketed at teenagers and young adults who appreciated them a lot. Most of these shows had around six seasons so they must have been doing something right! Personally I think this show was fantastic and I hope we get it on DVD soon :-)
