I thought it was all a bit contrived, and yes, those amazed smiles as the new nanny appeared as though she was an angel from heaven, seemed ....just odd. You would want an older more experienced nanny and not some flaky girl.Caroline is annoying [always] and wants her own way in everything.John is charming and unreliable, Judith is an achoholic,
Gillian is also selfish and stubborn as well [and the opposite of charming] Alun is just weak about almost everything, Rafe and his girlfriend say bizarre things [their baby, Calamity?Fantasy land.] Harry [the old friend] speaks a lot, about nothing in particular,Gary, the son [of Alun] has something dark in him despite the smiles..... in short, it's great tv.
