The movie is a guaranteed nice time if you are looking for this sort of "eurocrime" stuff. But personally I thought it was a bit dramatic.
The heroin addicted girl and her mom stood out for me. Much more than the whole "training the younger cop thing". Also, for an one hour and a half lenght movie, which we already knew who the bad guy was and what he was doing, the time should have been filled with more people being subjected to a beating.
However, I may say that, when it came down to shootings and car chases, the movie delivered the goods. Perhaps they should have worked more on the bad guys characters, so they could've looked more... "exotic", let's point this way.
It was not the best italian cop tale, but I would watch more of the "Mark, the narc" series.
