I saw this yesterday and was really annoyed with whole film! Campbell was such a major character in the book and he had like half a dozer scenes in the film, where was the lady who became his girlfriend??? (Can't remember her name, sorry!) I adore Jodi's books and this is the 2nd one I have seen ruined. Ordered The Pact, totally awful.
One of the main reasons I went was to see film was to see the impact of the ending on the audience who haven't read the book, and was utterly dissapointed. The ending of the book MADE the story and I was so shocked it was cut out.
Personally I found it a complete waste of time. The acting was amazing and i give full on credit to the girl playing Kate, but if I knew how it was going to end, I would of never have gone to see it. Jodi's books should be left alone unless they are going to keep in the vital parts of the story
