My Sister's Keeper

What does this film, which tells the story of Anna a so called ‘savior child,’ conceived expressly for the purpose of saving her older sister’s life via stem cell and organ donations, tell us about the conflicted nature of parental obligations in such situations? How does it illustrate Kantian strictures against using people merely as means? How does the case of Kate and Anna compare with historically significant cases such as that of Terry Schiavo and Ramon Sampedro? What roles do such stories play in the world of young adult literature, and introducing teens to difficult ethical issues? Do such works of fiction cross moral lines in capitalizing on such situations?
