It's quite nice the way they manage to shift the viewers' perspective on whom to hate:
First we (I) know that the husband isn't a killer
Then I began to suspect him because of his affair and feel quite annoyed by him
Then because of the way he reacts to the cops you begin to realize that he is innocent and it was obviously someone else who has killed or kidnapped her
Then we see that the women is still alive and although I realized what that woman was doing was wrong, maybe he deserved a bit of torture
Meanwhile we begin to hate the media and the people who are blaming him; also we have to sympathize with her a bit for having such a terrible mother/parents. I also felt sorry for her for getting robbed
Then you see that she has done this before, so you want to bitch to get caught
and then the then .........
Anyway, although it would have been a bit cliche if she got caught in the end and I would have felt a bit bad if she got caught after all her planning, there is a part that sits very uncomfortably in the back of my head for the way it ended. Those two poor men.
