I thought the book was excellent. Watched the movie for the first time last night and didn't think much of it. It didn't do the book any justice at all, it left loads of important stuff out. I thought they covered the ending in the movie much better than they did in the book having said that. It really showed him dying a slow and painful death, which may not be our type of justice, but it was nice to see all the same 
They left loads of lovely touches out, like the actual passage of time, what the 'in between' was really like...the part where she met other people who had died during her time there, including the family dog. Didn't the mother have an affair with the policeman? They didn't go near that either. Also, I thought they found the bracelet? I knew he threw the main part away, but I thought someone found the part he kept?
