Samantha Morton may well have deserved to win an Oscar based on this performance, but having seen the film again on the small screen I take comfort from the certain knowledge that she will one day win. Her performance as a grieving mother holding together her family and herself is subtle, moving and very powerful.
However, the role would mean nothing if she was not ably supported, and this is one of those films in which every single character extracts such realism that it is hard to believe that the dialogue spoken was ever just words on a piece of paper.
Paddy Considine is magnificent as the husband and father of a loving family that is breaking down from the inside, whilst struggling to find a role within this blackened unit.
But, the real wonder and find of this film are the two young girls.
Being real life sisters may have helped but, my god, they played with such resonance, such force that when watching the hospital scene I cried.
And I rarely cry.
