For those of you who have no idea what it's about, basically a little girls parents decide to genetically engineer another pregnancy as a perfect match so that they can prolong/save her life as she has a rare form of Leukaemia. Basically create a spare parts child. Then, later down the track, the 'parts' child sues her parents for the rights to her own body, and the choice to refuse invasive medical treatments if she wishes.
Obviously, with a child cancer involved, it's a bit tough to watch at times. They did a bloody good job of making the girl with Leukaemia look like crap as her condition deteriorated. It poses a lot of moral questions, and makes you think... If you were in that position, would you engineer another child to help save the life of another? Well, probably. You just would, wouldn't you?
It also shows the inner family tension that comes with a terminally sick child - stress between the parents as they differ in opinions, a mother giving up her life to strive for the survival of her child at the cost of her other children being left out and ignored/forgotten, each of them struggling in their own way. You want to disagree with their choices, but you can totally understand them, and in fact, would probably go down that track yourself if put in that position.
I think the reason that it's so upsetting to watch, is because it's so REAL.
Here's hoping none of us have to go down that track. Ever.
