The show is slow but the payoff is rarely worth it. It will dig its claws (not even claws, maybe trimmed nails) into you after an endless wait and then not have a truly eventful reward at the end.
The characters lack any sense of decision making and common sense half the time. I was 4 episodes in and they still hadn't asked the lady what year she thought it was.
And that sums up the show, things that could make for decent drama and can be moved fairly quickly are drawn out and have you screaming at your television for 8 episodes.
The foundation has potential, but the execution falls flat on countless occasions.
