I'm not sure if my readers are fans of this show but I like it. It's definitely unique. I love all the different characters, from vampires, witches, werewolves, Frankenstein's monsters, and even Dorian Gray.
Last night's episode featured Patti Lupone as a "good" witch. It was a great episode. She explains to the character Vanessa that the difference between the good and evil practitioners, called day-walkers and night-comers, are that the evil practitioners sell their soul to Satan. Patti Lupone's character reveals that Vanessa is in fact a day-walker, and she adds that she is the most powerful day-walker she has ever come across.
In one scene, Patti Lupone's character is taking Vanessa on a walk in the forest to gather herbs. She picks some comfrey leaf and asks Vanessa if she knows what it's used for. Vanessa answers that it's used for safety in travel.
If you haven't seen the show yet then I would highly recommend it.
