A TV series that is available on Netflix that I have been watching recently is Grimm. I think it's quite good so far, I've watched 2 or 3 episodes something like that. The show is similar to what I regard as the trailblazer show of the type, Buffy the Vampire Slayer, because it is set in modern America but has fantasy elements - similar to the Grimm Fairy Tales. So, it's the classic good v evil set up. The good guy is a police detective who has a partner but the partner is unaware that his colleague is also a kind of guardian who has knowledge of evil creatures passed down through the generations of his family. If you like fantasy and mild horror then I think you'd enjoy Grimm.
