The first season of the show was such a solid and thought provoking one, but its kinda sad how the later seasons turned out to be. Season 2 was ok for me and season 3 was also entertaining. But for me they really spiralled downwards in the final one. In no way it needed an hour long 9 episodes with an hour and a half finale, they simply dragged it for no reason. I really wish they had kept this show a one season deal only as it was splendid.
