It's been a rough week for the Archieverse. Just days after The CW pulled the plug on Riverdale spinoff Katy Keene, Netflix has gone and cancelled fellow sister series Chilling Adventures of Sabrina after two super-sized seasons (or four parts).

`Working on Chilling Adventures of Sabrina has been an incredible honor from Day One,` said showrunner Roberto Aguirre-Sacasa in a statement. `The cast, beginning with Kiernan as everyone's favorite teen witch, has been an absolute joy. I am beyond thankful to the crew, writers, editors, assistants, and everyone for pouring so much love into this dark dream of a show. I'm also grateful to our partners at Netflix, Warner Bros., Berlanti Television and Archie Comics for letting us tell the story we wanted to tell, the way we wanted to tell it. We can't wait for everyone to see Part Four.`

Originally in development at The CW as a companion to Riverdale, Sabrina eventually moved to Netflix, where it scored a 20-episode straight-to-series order. It premiered on the streamer in Oct. 2018. A second season of 16 episodes was subsequently ordered, the first eight of which dropped in January.
