I suppose the book is more interesting, because there is not enough detail to link Dave's abduction to his personality transformation, perhaps a scene after his abduction could have done the story justice. The plot line is predictable. The are no connections between the first and last scene, yet it forces you that it is, like " I wish Dave would have never gotten on that car", what? really? The story revolves around Katie's murder, but somehow it makes you belief that the Abduction has something to do with it. Not a good adoption, good acting tho.
