Three star only for season one and that because of the acting of the brilliant casts, i was exited to watch second season and to my surprise that was boring so I skipped the whole season then I started to watch season three because of the casts but again it was boring as hell , I wasted my 6 hours to see the ending , I even skipped the second last episode of the third season and you know what it seemed like I didnt even miss anything of the story. What kind of a didective solve their case at age of 70 and the ending is so dull that I regreted for a week to spend my time on this . Season one amazing all other season seems forced.
