What a load of far fetched, unbelievable, rubbish. Certainly not true to the era it is supposed to be set in. A fish-gutters house in Victorian times that appeared to have electric lighting, 'undercrackers' a term that didn't come into being until relatively recently. It's absolutely farcical.
I have watched two episodes in the hope it would improve - sadly not.
The cast are not right, they are too close in age to be parents of children that age and surprised to see a great actress, Julie Graham, putting her name to this.
