Been wanting to see, since saw trailer. Trailer shows an exhausted Mum with a newborn and two older children, getting a night nanny. The night nanny seems far too good to be true; you know there is going to be a twist. The film keeps you guessing almost to the end before revealing.
It has been criticised for not saying that the boy was autistic and the Mother had post natal depression, but I like that a person is not just their condition. Yes it romanticises post natal depression and does not make it clear how to handle / treat BUT this is not a documentary or educational film; it is a film for entertainment.
It entertained me! It has additionally prompted discussions about post natal depression.
