Thanks for pointing this out, Ravens... I hadn't heard of this one (and here I thought I had my pulse on the heartbeat of horror TV). Hard to tell exactly what the series will be all about, but I see some interesting themes and images going on in this trailer. I'm a sucker for a darkly gothic period movies/shows, especially Victorian era stuff.
And you're right, this is apparently a "limited series" with only 10 episodes planned at this point. If it's not going to be an ongoing show, that might be okay with me. My TV watching schedule already has quite a few dark dramas (some of which also have vampires).
