Edge of Darkness (2010) Storyline: Thomas Craven is a detective who has spent years working the streets of Boston. When his own daughter is killed outside his own home, Craven soon realizes that her death is only one piece of an intriguing puzzle filled with corruption and conspiracy, and it falls to him to discover who is behind the crime. IMDB Review: It's not giving anything away to say that the story is about Mel Gibson's character trying to find out who killed his daughter as that much is in the trailer. Mel plays a veteran detective and so has skills and resources we civilians don't. The movie takes a while to develop and takes great pains to show the love of Craven for his daughter in the opening scenes and then periodically remind us in flashbacks. There are a lot of characters which seem to be critical to building the intrigue of the movie; activists, defense contractors, government officials and various henchmen. The movie does a good job for a while of hiding who is working for whom. Suspense does build for most of the movie but a good bit before the end it is evident what is going on and the movie shifts from an action thriller to more of an pure action movie. ~Mark Smith
