I must admit I was into the revenge and rooting for the Bad Guy... Who actually turned out not to be a "Law Abiding Citizen", but a actual bad guy! So you wonder is that why Ames & Darby targeted his family and it wasnt isolated incident !?!?
The movie plot was a great thought, but then something flipped! It appeared to me, my spouse and a couple friend of ours that they must have ran out of money and had to RUSH the end! Way to unrealistic at the end. But what movie doesnt stretch reality?
