I watched the 1st season of it a few years ago (netflix). Was OK, but I tired of it, and it was too "soap opera" for me.Do you mean the old black and white TV show? It was a classic for sure.
The movie with Depp was interesting too. Based on that setting.
But I seldom watch entire series, I just don't watch enough TV (busy mixing? lol).
The one I do watch when/if it ever comes back is "What we do in the shadows"...which is another vampire thing. Offensive maybe for some, but hilarious. Recommended for the not-easily-offended.
