I seemed to spend most of it shouting at Gemma Whelan (who I love & why I watched this) to get dressed! She spends a lot in time in a tiny shortie nightie, wellies & thick coat, at one time complaining that the (non existent) frost had got her sprouts! If it was that cold - and cold enough for her husband to wear a woolly hat in bed - she'd be wearing nice warm pyjamas. Don't know why that bugged me, but it did!
I felt that some parts of the story were unresolved - something would happen either without explaining why or how, or it wouldn't be discussed again. And then everything suddenly became all right again.
Based on some other reviews I guess it might have been edited for TV.
Interesting if you want a glimpse into 3 days in the lives of a dysfunctional family, but not if you want a "traditional" nice & tidy Hallmark-type Christmas movie.
