Fans are urging The CW to renew its Supernatural prequel, The Winchesters, as fears of cancellation grow. The show, produced and narrated by Jensen Ackles, follows the parents of Sam and Dean Winchester in their younger years. With Walker: Independence already cancelled, The Winchesters is the only remaining connection to the popular franchise that dominated the network for nearly two decades. Despite being highly rated, renewal has been complicated by the AMPTP-WGA writers strike.
