Notice that this family is Muslim and Asian.
You can't do it with white people any more because most of them have no family and most of them have no manners.
All the social comedy from this series comes from people having appearances to keep up and a father who heads the household.
That is why no white family will ever feature in this kind of comedy again.
Perhaps a sitcom might be made out of couple one of whom is a Muslim and the other a BNP member?
Lots of potential for pub and pork jokes.
