Balkan probably gives her best performance to date to create a woman tormented by instability, sexual drive and psycho demons -- disjointedly portrayed in the script.

A paranoid police procedural, a perverse parable about the corrupting elements of power, and a candidate for the greatest predated Patriot Act movie ever, Elio Petri's stunning thriller makes no attempt to hide the culprit behind the film's grisly murder.

Petri's visually flamboyant film turns into a heady mix of Marx, Freud, Wilhelm Reich, and Brecht, with a bit of Dashiell Hammett thrown into the blender.

The movie survives beautifully both as an elegant thriller and as a study of the twisted infantilism that shapes the fanatic heart.

A provocative political thriller that is as troubling today as when it came out in 1970. Maybe more so.

The film may have dated as a cautionary left-wing tale, yet it has stayed fresh as a study in the minutiae of power. [1 Oct. 2012, p.85]

Although Mr. Petri quite consciously makes movies about ideas, he has, in his "Investigation," made a movie in which the ideas, and the man who seethes with them, have the shock and impact of the most fundamental kind of melodrama.

A piercing satire of Italian investigative techniques, and an interesting meditation on the relationship between class and guilt.

As specific as the film is to Italy at the turn of the turbulent 1970s, it’s also a film about how power first corrupts, then makes mad those who possess it.

Like all good directors who make films about their own obsessions, Petri transmits an obsessive feeling in the film itself. "Investigation of a Citizen" is stylistically disconnected, but it works because it is absolutely fascinated with the nature of the inspector.
