My favorite tv show from year 2015. I do not watch many tv shows under the Action category, but this was great and now I am bigger fan of tv shows of this kind. Nowadays, fresh tv shows entering the cinemas, do not have 'something' what this tv show got. It wasn't easy to leave the cinema, when I saw it first time. What determines the phenomenon of this tv show? It's realism, taking care of psychological probability?. I hope you're excited, so start watching it now!.
