My Sister's Keeper

Went to the movies yesterday and finally saw Angels and Demons before it leaves the theatres. Saw an ad for Jodi Picoult's My Sister's Keeper coming soon! So exciting! It is a fabulous book on a heart-wrenching topic, but don't you always get worried when they turn a book into a movie? It becomes the director's POV, not yours as you imagine as you read. From the trailers it looked like it's the same story. Has anyone seen it yet? Is it out in the rest of the world????
