What keeps this movie from being good
Is that once the detective lets Wendice "know" about the blackmail, Wendice barely questions the detective or Mark. He should have acted more upset. He should have screamed at Mark, or mentioned the betrayal, specially when Mark suggested that he should lie to save his cheating wife. The nerve! I really wish Tony would have framed Mark. It would have been the best punishment for both of the cheaters.
And I found the lack of sympathy of the inspector over the affair appalling. It's like he was almost for Mark and Margot. It really sucks Mark got no punishment at all.
