This movie is not as good as the books. The acting could have been better, the staging crime scene was different to in the book (in the book, there were traces, but the blood was not visible, the kettle was on) the clues were different, and it missed the scene where Amy made Nick anniversary breakfast.
I did love the effects of the music though, the music made it sound mystic, mysterious, effect, and that's how it's supposed to be, because this story is supposed to chill your spine a little, leave you begging to know what will happen next. I didn't like the movie that much. If you want to know the story, read the book! it's so much better
