This was a recent Showtime series. I just finished it up on Netflix. It's a mash-up of different weird/horror fantasy characters woven together in to a common story arc. Vampires, witches, Frankenstein and Dorian Gray to name just a few pieces without spoiling anything. Yes, League of Extraordinary Gentleman pulled a lot of these things together but I would say this is better.
It isn't perfect, it is weird. My wife dislikes scary stuff but even she got invested in to the story/characters. There were parts where things got so weird she looked at me and said, "Really!?"
