One thing drove me nuts
Great performances by one and all, but what drove me up the wall is that 14 frigging years later, she hasn't changed the locks in her house and the guy can just use his key and wander in any time, day or night - unless she didn't lock her doors, which I find highly unlikely.
Every time he showed up I almost yelled at her to call a locksmith.
It may have been one of those movie devices to add sinister air to him, as in a write-up on the real story, during her divorce from him, she called the cops as she thought she was poisoned. He even admitted it, she didn't press charges, and yet she kept up a relationship?
