I don't know why this movie didn't get better reviews,I thought it was really good. A bit over the top if you are squeemish, but intense throughout and you most definately need to be paying attention. I can agree with the comments about it being unrealistic, but come on, this is a movie not a documentary.
The legal thriller meets the serial-killer shocker in Law Abiding Citizen. The story begins when home invaders kill Clyde Shelton's wife and daughter. The bereaved father (played by a thoroughly unsympathetic Gerard Butler) looks to slick Philly prosecutor Nick Rice (a low-key Jamie Foxx) to see that they receive the maximum sentence. Instead, the murderer, Ames, testifies against his accomplice, Darby, who gets the chair, while he gets 10 years. Upon his release, Ames' mutilated body turns up in an abandoned warehouse, and all roads lead to Shelton. Rice attempts to defend him, but his client makes it impossible--Shelton wants to go to prison--so he does time, but then members of Rice’s legal team start to die. The attorney suspects Shelton, but can't connect him to the crimes, so he races against the clock to save the lives of his assistant, Sarah (Leslie Bibb), D.A. Jonas (Bruce McGill), and his own wife and child.
