If you want a show that doesn't push the envelope and is appropriate for the whole family, watch "Sister, Sister"! Some of today's kids' shows are extremely edgy compared to "Sister, Sister". What's worse is that many of these kids' shows are rated TV-Y7, meaning a network feels their show is appropriate for children 7 and over. Some parents have issues with that due to iffy content present in some kids' shows. "Sister, Sister" has never been rated TV-Y7 despite its true wholesomeness; it's rated TV-G on ABC Family and TV-PG on WGN.
I don't care for "Family Sitcoms" as they tend to be too sappy and intelligence insulting farce. Sister, Sister is not. I grew up watching the series (granted on Disney Channel, not ABC) and this show is a nice compromise between family comedy and sappy shows. It manages to create fun, quirky characters that don't act incredibly unrealistic. The parents are also not side shafted in favor of the teen and their comedy is just a smart and sharply written. They feel closer to real people then the unrealistic families of Full House and friends.
