I'd say that something like Modern Family is a more accurate representation of family dynamics. Or even The Simpsons or Roseanne, which is why we moved towards those types of shows and away from 80s-type family sitcoms in the first place. I don't think I've ever encountered a family that wasn't "dysfunctional."
Agreed. My family was dysfunctional, as are a lot of families, and I've never understood where TV got the idea that they were anything like what was on TV in the 50's, 60's, and 70's. Cosby might succeed with this show on INSP, Bounce TV, or The Disney Channel, but I don't think that it will work on network TV.
