gincamelback: "Sorry if already said, but while I like the programme, I think it very much smacks of the two sisters writing Really Good Lines and high giving each other on their insight or wit, rather than them writing realistic dialogue."
That is exactly the problem with it. It's a series of amusing one-liners: the comedy doesn't arise out of people's character - in fact, the characters are largely interchangeable as they are all capable of coming out with witty statements at any moment.
I had to switch off 10 minutes into episode 2. So many things wrong with it, but take one example: the mum has arranged a series of disagreeable things for herself such as having a smear test. One of the girls suddenly says: it must be mum's birthday, because she always arranges to do things she doesn't like for her birthday.
But how does this make sense? No-one always books horrible things for themselves on their birthday - why would they? And why have none of the girls - who seem to be mostly early-to-mid teens - remembered that it's her birthday? One of them would, surely?
