First off, I didn't read the book but know it ended differently. It took every ounce of courage I could muster to see this movie. My 14 year old daughter died of cancer last year. I can't speak to the accuracy of the legal proceedings in this movie, but the portrayal of what the children and families fighting cancer go through - treatments, side effects physically and emotionally - are completely realistic. Everyone should see this movie and realize this is not just a Hollywood production - what you see on the screen is happening to kids every day.
