Claes Bang is absolutely delicious as Dracula, I really liked him in the part and Dolly Wells just brilliant as Agata Van Helsing.
Episode one had me gripped, episode 2 was brilliant, except had the unwelcome wiff of the BBC fitting it's agendas in, but episode 3, as others have mentioned and I wanted to test, was indeed an absolute train wreck. Not only did it completely fail the first two, it was almost a different programme and the BBC, of course, got their agendas in there. Just awful, with a rotten ending to finish it. Watch the first two, don't ruin it with the third.
10/10 for the first two, 0 for the third.
