The Winchesters, a Supernatural Prequel, Denied Second Season After CW Cancellation. Warner Bros. Television's attempts to find a new home for the show have been unsuccessful, despite a #SaveTheWinchesters campaign led by Jensen Ackles. The CW's focus on unscripted and lower-cost programming led to the cancellation of several scripted series, including The Winchesters. Despite potential ties to streaming platforms like HBO Max, Netflix, and Amazon Studios, none of them picked up the show. Other CW shows like Superman & Lois and All American: Homecoming remain in uncertain territory.
