This is the archetypal woman's film - but there's nothing wrong with that, with far too few opportunities for women in the key roles in movie-making. So women fill the slots of scriptwriter (the British Morwenna Banks), director (American Catherine Hardwicke) and the two top acting positions (Australian Toni Collette and American Drew Barrymore).
And the subject material is feminine too: breast cancer, infertility, and female friendship. Like "The Fault In Our Stars", this is a frank exposition of what it is like to suffer cancer - in this case, with chemotherapy and its attendant sickness, tiredness and hair loss followed by headaches, vision loss, and pain.
It sounds tough and it is - one the saddest film I've seen in a long while - but there is humour and warmth and superior acting which make it worth viewing this real slice of life. After all, most of us of a certain age have had relatives or friends who have suffered one form of cancer or another, some surviving, some not.
