Well, the employment of blind persons within a police per se is not too uncommon, but their tasks are hardly in the field or participation in chases... The background and circumstances are explained, convincing at first, but as the story develops and bearing in mind the real wrongdoer the reasons begin to feel odd. Several cliches regarding disabilities, superior-subordinate relations and police inattention are present too much, plus the flashbacks explaining the cause of blindness are too protracted and overlapping. 1.5 hours per episode is evidently too long as well.
Yet, the performances are pleasant (Maria Chiara Giannetta, Enzo Paci, above all) and there is a pleasant symbiosis of one episode - one case and the leitmotif, elevated by beautiful Italian views... But as something was missing / not present for me (incl. No real chemistry between Blanca and Michele) and I surmised the wrongdoer too early, I would rate it with 7 points as I could name dozens of meatier Italian police series.
