Not dark enough for Riverdale. On that show she would be an occult serial killer. Her first victim was Salem the cat. He couldn't really talk but she thought he could. Sometimes he still does.
Nothing they could do could compare to the recent "Chilling Adventures of Sabrina" comic series, which is the basic story, half-witch half-human Sabrina being raised by her two aunts, set in the 1960s, but with some, ah...differences.
Hot damn! For something I give zero fucks about, I have to hand it to Archie's, uhh, multiverse? I mean it's not like they turned Josie and the Pussycats into mid-90s heroin addicts, right?
