The first Supernatural spinoff arrived earlier than many fans realize, but it succeeded by keeping things simple and sticking to what made the original show iconic. While the short-lived 2022 prequel The Winchesters attempted to expand the Supernatural universe with new characters, time travel, and lore-heavy mysteries, one earlier attempt at a spinoff did the exact opposite - and arguably got much closer to what fans actually wanted. Supernatural: The Animation may not be a household name even among the most devoted hunters, but its approach to continuing the Winchester story hit far closer to the mark than The Winchesters ever did.
