I absolutely loved this film. I really enjoyed reading the book as well, and obviously the book format isn't particularly easy to pull off in film-form, but I think they manage to do it really well! I enjoy the fact that the main female character is so complex and really not the stereotypical woman that we are normally presented with in movies. She's very detached, almost evil and willing to do anything for self-preservation but you still feel some kind of attachment towards her which is incredible that they're able to do that. The premise is that a man returns home one day, on their anniversary, and his wife is gone. He then calls the police, but they believe him to be the main suspect and he must try and prove that he didn't murder his wife.
