I loved it. Not read the book and not usually a Cumberbatch fan, but I thought it was brilliant. The idea of children living on somewhere, caught between worlds, whether before they are born, when they are lost or die, or when we become adults.
I absolutely sobbed at the end, when he took her hand, and seemed to have made his peace with the fact that she is somewhere, somehow still with them, still a part of them, just as she always was. Seeing his son looking at him on the tube from another place in time on the way to the hospital was beautiful.
It reminded me of spirit babies, i'm not much for woo normally, but I believe that my middle child has been with me before, it's too personal to explain, but the minute he was born, I knew when I had last been with him, and now he was finally home. Child in Time is a perfect way to describe it.
