This is a poor attempt to copy "Montalbano", right down to the quirky cop at the entrance to the police station. The characters are not as rich as many other detective series. Attempts are made to make them seem interesting by giving them problems and issues with which they deal outside of work. As with many French and Italian series, there is the inevitable lesbian relationship (one seldom sees gay male relationships, maybe because they with to preserve the image of Machismo or the French lover, who knows). The episodes drag, and become very formula driven as the series progresses. The sets are either very grubby, crumbling old buildings, or crumbling old buildings filled with ornate carvings, frescoes and furniture.....very Italian!
It's watchable but just expect mediocrity, nothing else!
