Admittedly, had seen the movie several times before reading the novel. I love the movie. The novel varies in major ways. You shouldn't pick it up if you want to love the characters, but you should if you want a good thriller to guess where it'll go. I struggle with the pace, because it moves pretty quickly but also slowly during some sections. Overall, not bad i was invested enough.
