Written by Riverdale showrunner and Archie Comics CCO Roberto Aguirre-Sacas, the to-be-released Sabrina show isn't going to be a lighthearted romp about a high school student who happens to have magical powers. Both "Riverdale" and "Sabrina" are based on Archie Comics properties, and there presumably would have been opportunities for characters to cross over between the two shows had it landed at the network. The Hollywood Reporter announced that Sabrina will be heading to Netflix and has already earned itself a two-season twenty-episode order.
In the introduction to Chilling Adventures' original collected edition, Aguirre-Sacasa said this of the comics' tone: "If Afterlife with Archie was about Lovecraft and zombies and body horror, Sabrina would be more psychological, a bit more subtle (but only a bit), a bit more sexual (as stories about witches often are)". Perhaps streaming results from Riverdale appearing on Netflix enticed the streaming giant to make a move in acquiring Sabrina for themselves. TV will retain total ownership of the Sabrina series, whereas "Riverdale" is a co-production with CBS TV Studios.
After Netflix saw how people responded to Stranger Things' second season by making even more memes than the first, and presumably saw how much people talk about Riverdale weekly, why not shoot for the next big thing? The show, which tells the dark origin story of Sabrina in Riverdale's neighboring town of Greendale, follows Sabrina as she tries to balance being half-witch and half-mortal while fighting against the evil forces threatening her, her family, and the world. According to Variety, Warner Bros.
A dark drama in the horror genre, the new Sabrina series is worlds away from the bubbly 1996 Sabrina, the Teenage Witch comedy series starring Melissa Joan Hart. No word on if that plan has changed now that the show has jumped from The CW to Netflix. However, that list is likely to be reconsidered now that the show is moving to Netflix.
