This film is a blast! It's got tons of great action set pieces in it (the car going off the cliff and the carnage inside it was a high point) and it even has a very satisfying conclusion with the crippled kid from Violent Naples.
I've been itching to see some more hard-boiled polizia action and this is a top drawer number.
I recognised the bloke who played the child abductor from somewhere, can't remember which movie it is though, the scenes in the prison involving him brought a couple of tears to the eyes
