As other reviewers have mentioned, the first few episodes of this series is AMAZING but becomes poorly contrived towards the end (not just the final episode but about halfway through). By episode 3, I thought this was the best, most thrilling series I had seen in a long time, but by 5, I was ready for it to end. Richard Madden does an incredible acting job (and those looks don't hurt). SOMEWHAT SPOILER: The twist ending made the whole series feel cheap.
