"The Cynic, the Rat and the Fist" is definitely one of the better Poliziotteschi flicks. These movies are usually boring, incomprehensible wastes of time for everybody concerned. "Cynic" is head and shoulders ahead of the pack because it is actually consistently entertaining, though I was still confused and left in the dark for parts of it. It also has legendary actor Tomas Milian as the bad guy, though he isn't as memorable here as he was in the classic Eurocrime, "Almost Human".
The movie has a lot of action, but not so much violence. What do I mean by that? There are a lot of punches thrown in the movie, not to mention slaps and backhands, and actors convincingly take these blows when they topple over backwards. However, it often doesn't look real. You can tell the blows didn't really connect, and nor is there much make-up work to depict bruises as a result of them.
There is one shocking scene in which a woman has acid thrown in her face. It wouldn't be an Italian crime flick without a surplus of violence against women. I think every woman in the movie gets roughed up somehow. Interestingly, there is a scene where the hero reacts unfavourably to a guy beating a prostitute. There is so much violence against women in these movies - and particularly movies by the director, Umberto Lenzi - that you feel obliged to assume that he was a proponent of it. Of course, the hero later gets his own hands dirty in this regard later in the flick.
Be on the look out for a ridiculous scene later in the movie where the hero and some other guy break into a building that uses invisible laser beams for security, and you can clearly tell that, when they appear, these laser beams are made out of string.
