It's my guilty pleasure. I love it.
My favourites are the Siddiquis who are just gentle and witty.
The ones I never got the point of are the Moffats. The parents in total thrall to Scarlet and never actually commented on any programme other than to agree with her, or the mother telling her "you did that" and the younger daughter trying to be Scarlett. The Dad looking on like he'd rather be elsewhere.
