This one really pushes the envelope on "ends justify the means" police tactics, even compared to the other Italian cop-thrillers I've seen. The two protagonists are cops who belong to an "anti-gang" squad...that means, in this case, that they actually act like gangsters. They're nihilistic, sexist a-holes. They like blowing things up for fun. They shoot criminals BEFORE they commit crimes. A gangster wants them out of the picture and has one of their colleagues shot; from there on, they actively engage in gang warfare. That's the plot.
The dialog is not at all clever. The premise is set up lazily and has no authenticity to it. The musical score is light-weight, typical 70's cop-thriller fare.
It's consistently entertaining, however. Whether laughing out loud or gasping in shock, I was never bored. There's plenty of eye-popping violence on a level with "Violent Naples" to satisfy fans in that department. The ending is very abrupt, surprising, and cool; it gives the whole rest of the movie a darker tone.
I definitely recommend it to fans of violent, Italian cop-thrillers from the 1970's, or any violent cop-thrillers from the 1970's, or good, trashy movies in general.
