It's my favorite book by Jodi Picoult(I've read most of her books) and I still get emotional over it.
I did read that the ending was going to change which would completely ruin the whole story IMO. I do plan to go see it,but I am not expecting it to be anywhere as good as the book. I also hate the fact that Cameron Diaz is playing the Mom. Sorry, I just can't see her pulling this off at all.
