Fantastic to me…. The acting , the suspense, the most intriguing relationships in marriage. It seemed to me at some stage that Bens tolerating her constant cheating was making her angry and contrary to what she was showing deep down , she hated him for not controlling her. As if she wanted to push him , to test how far and how long she can hurt him without being punished… And a very logical end to the whole concept of unpunished killings. They had to end , only maybe not the way it did. After all the killer wasn’t punished.
