I've just watched this on catch up. I liked it too, it was beautifully shot. Matthew Rhys stole the show I thought.
I do have a problem in that Dornan played the part of a murderer in another drama, and I keep looking into his eyes and wondering if there is evil behind such a gorgeous facade
Do you mean The Fall? I really fancied him in that even though he was a murdering psychopath but haven't fancied him in anything I've seen him in since. There must be something wrong with me! 
Looking forward to the next episode.
