This tv show has a unique quality i never saw in a serialized drama : every episode is different even they are telling the same story with the same characters,take as an example the last two episodes, they are different as the night and rhe day, but they have the same quality, the episodes are switching from a good futuristic police story to a nostalgic reminescence of the past, from war to the best of the human kind, from cities to the mountains and stars, it still manages to make me to remain with my jaw dropping at the end of each of the episodes and the actors are so good i could easely see them in a movie with chances for an Oscar.
