I watched the first episode and it was good!
Surprised by Ricky Whittle's suitability for the role, he comes over quite well.
From what I can remember, other than the graveyard offer, follows the book fairly well.
A good start, 9/10. I shall be tuning in next week!
Edit: I watched the whole thing in HD, and only realised 4k was available after I'd finished. Had to check it out of course, and the 4k stream does give you a much better picture.
