My Sister's Keeper (2009) - 7/10
The book of this is one of my favourites. If I was reviewing that it'd get a 10. The film is a fairly good representation of that, but of course Hollywood decided that certain things need changing, and there are things left out, which is necessary to keep the film length down. It's worth watching but if you have the time to read the book I recommend doing that before watching this.
