Well, from the times that I've seen the show, it does all seem to be fiction. Even if some things have a *hint* of truth to them, that's all it really is. For instance, using candles for rituals and spells, yes Wiccans/Pagans use candles for rituals/spells. Although if the actual spell itself is used by Wiccans/Pagans, probably not; and I've never seen an episode where she does a ritual for a holiday or just to honor a deity, and that in itself is where one of the major flaws is. I myself am not Wiccan, so I can't tell you definitely whether something IS or ISN'T Wiccan with much certainty, but what I will tell you is this: it's definitely NOT all about the spells and magick. It's a *spiritual path* dedicated to worship of a deity or deities of old. Spells are nothing more than a small part of that. Also, I don't know if it has ever been on the show, but usually most good hollywood witchcraft shows and movies will include one particle of truth called the Wiccan Rede: "An it harm none, do as ye will" If you've seen that in the show, that IS a true element of Wicca, but probably not much else.
