La vendetta è mia

I think this movie is an all around tour-de-force depiction of a sociopath. All aspects of this movie are superb. The main actor gives a truly chilling and convincing portrayal of a man with no conscience, at the same time giving his character great depth and complexity. Aside from being based on true events, this cold blooded murderer is much more realistic than the clever game-playing types portrayed in such films as "Silence of the Lambs". I would highly recommend this movie to all but the squeamish.
