My wife and I watched all 4 seasons (48 episodes) and we both thoroughly enjoyed the series which is usual as we often don't like the same shows. It had interesting murder plots in most all episodes mixed with an ongoing family related mystery theme that weaved through all four seasons. The cast and acting was decent and the Turin area scenery was scenic and interesting. While there was a lot of in-office romantic nonsense among the key players, as well as questionable procedural practices at times, the cast and plots kept things moving for us both. My wife liked the romantic stuff more than me and I enjoyed the many attractive Italian women who appeared throughout. The final episode was a bit of a disappointment to us both and we wondered what the writers and producers were thinking with a series wrap like that. Two thumbs up anyway.
