[HitIer]

A detective cat/mouse thriller about a goal driven psychopathic killer who is fed up with the justice system imprisons himself to avoid incrimination for all his murders inflicted upon those who are guilty in his eyes. The police are aware it is him but lack the evidence to persecute him, and the movie eventually ends after the deaths of many. Finally, when he is about to kill those at the very top, the investigators discover his killing device and use it against him, which results in him dying a sad, tragic death.

The movie I'm talking about, is of course Law Abiding Citizen.

Too bad they didn't cite it though, not even as an inspiration.

that happens very often
and even if they did cite it, or the director acknowledged the inspiration like Pacific Rim, it wouldnt matter
