The acting is really flat! It shares this kind of very predictable acting with many other Italian "fictions", it also lacks realism in depicting the general atmosphere in Italian policing, which is a bit tougher and noisier than it appears here. They also seem to have saved on extras, there are these deserted street scenes, and yes, it is set in Arezzo a not very big town in Tuscany, but it is generally a more lively place than in this series! I mean Arezzo is a provincial capital, with proper traffic, bustling streets with plenty of cars and mopeds (anybody who's visited Italy can confirm this), none of this is apparent in the outdoor scenes. The music is also very predictable. The dog seems to be the only really smart guy and the best actor!
