My mother is perfectly fine with it, as she grew up on the show. My grandparents, on the other hand, oh, dear. XD My grandfather is pretty passive on the subject, but my grandmother has at some point become brainwashed to think that supernatural = Satanic. She's told my mother that we shouldn't watch DS, and she's made the ridiculous claim that had she known "what DS was about," she would have restricted it from being watched. She's even said negative things about The Wizard of Oz a few times. Go figure.
My uncle watched DS with my mother, and now he seems somewhat embarrassed about it for whatever reason. Probably doesn't want my cousins, who give him enough lip as is, the fodder of the fact that he watched a soap as a kid or something. Who knows?
