For U.S. sensibilities the way the Italians make TV may be a bit too much. That is exemplified here by the main character who apparently has zero morals when it comes to how he deals with and treats women.
I'm sure this will be off-putting for some viewers. The Italians, the French... well, either you have to get use to the way they portray some of the men in their shows, or you'll stop watching.
Schiavone is not a very likable guy in some ways. He smokes ALL THE TIME. He treats women badly. Nevertheless, I enjoyed watching the first season on Amazon Prime. If there comes a time the later seasons are available, I'm pretty sure I'll watch them as well.
All the sort of stock elements are there that are so perfected in Montalbano. In fact the resemblance becomes a bit uncanny (if not intentional). Rocco is sort of a mixture of Mimi and Salvo. Fazio is here. Pasquano is here. Caterella is here. The mountain scenery is beautiful, but it is not Sicily. It is maybe unfair that I say these things, but if you have not watched Montalbano, I'd recommend it before this show.
