Looks like the twist was, that there wasn't one, lol!
Thought it was good anyway,, gosh how unhinged was that Rachel...OMG...big chip on her shoulder from being not #1 anymore once the lil brother was born....now, I can understand sibling rivalry etc...from the eyes of a child, but come on, when you grow up then surely you should be able to see the situation for what it was?
littleelf, not a Nanny, but I don't think there is a reason for any Nanny to have to crap herself, it's a drama, but it did highlight maybe just how careful you must be, i.e. not just go by CV, but do the CRB, etc..which, I would think most people will do.
As for it's always the Nanny / Childminder, I think there are plenty of programmes that show the parrents as the Baddies, too, though. I think, if you are involved in a certain occupation then you are just bound to notice it more if there is another bad thing shown...i.e. plenty of programmes where Nurses, Doctors, Policement, Teachers and so on are shown in a bad light too, but you probably are more likeky to notice it when it's your profession...iykwim.
