The first 4 episodes are worthy of a 6.5-7 star rating. However, the ending is so terrible I'm giving it a 1 star rating. The ending comes out of nowhere (no, it's not a twist) with unnecessary explanation of a back story that hasn't even been hinted at during the other four episodes. The final episode spends about 5 minutes in an action scene and the rest of the episode is just a long, drawn out dialog about s*** that nobody should give two f***s about. It. Is. Terrible. Seriously, watch the first 4 episodes and then imagine what happens and it will be better than actually watching the last episode. The finale gave me brain cancer.
