My Sister's Keeper (film)

I caught this movie on the plane. What struck me was the plot. Biologically engineering a child so that parts of her can be donated to help her sister. She was not conceived by accident. Nor was she artificially conceived by childless parents wanting a child. She was artificially conceived to fulfill a purpose in life, that of prolonging the life of her sister.

Anna was raised to help Kate.

To Anna, what was her meaning in life? Her parents have made her meaning in life to be helping Kate.

When Kate dies, what happens to Anna? That is something the movie does not explore. Now that Anna has lost her original meaning for being, how is she is find a new meaning to her life?

(The book has a different ending, with Anna dying and Kate living. Guess that resolves the issue of having to explore what happens to Anna if Kate dies.)
