Unfaithful
This true-crime retelling is a true crime against storytelling. A married man discovers his wife is cheating on him, so he takes the man out of the picture himself. The couple then leaves the country to avoid prison. The final scene doesn't reveal whether or not he was ever caught for the crime...why?
Law Abiding Citizen
While otherwise well-liked, fans found the end of this movie as something to be desired. After getting his revenge on the people who wronged his dead wife, the hero turns himself over to the police. Yet he still somehow is able to blow up City Hall with a device that he was allowed to have in his cell!
