The film doesn't feature the greatest script ever written (not even the greatest script ever written for a trashy Italian film!), but the silly dialogue is often very funny and the film's absolute disregard for political correctness when it comes to the lead character's disfigurement is just great. Obviously, a lot of this film's success (or lack of) rests on the shoulders of Tomas Milian, and despite being given a rather heavy role; he doesn't manage to turn a great performance. His "Pigsty" character is a messy imitation of the "Garbage Can" character from Free Hand for a Tough Cop, while the hunchback character is a lot more like Milian's forte; but the make-up intrudes on the performance, and neither one comes off particularly well. However, I'd much rather have Tomas Milian in the role than anyone else, and he does always make the film worth watching in spite of its shortcomings. The plot flows nicely enough throughout and it's usually entertaining. Lenzi has also seen fit to throw in a sub-plot revolving around the hunchback's attitude towards his disability, which feels a bit odd but works fairly well nonetheless. Overall, this is a decent enough slice of Italian police action and I'm sure most people that see it will enjoy it.
