Mary and John Winchester, two beloved characters from the hit show Supernatural, were supposed to have their own spinoff series called The Winchesters. The show, produced by Jensen Ackles, who played Dean Winchester in the original series, was set to expand the Supernatural universe and delve into the backstory of the Winchester siblings' parents. Unfortunately, The CW recently announced that The Winchesters would not continue beyond its first season, joining the ranks of other canceled shows like Kung Fu and Walker: Independence.

The Winchesters took place years before the events of Supernatural and followed the adventures of young Mary and John as they battled monsters, ghosts, demons, and other supernatural creatures. This would eventually become the family business for their children. Ackles had big plans for the show and even had a five-season storyline mapped out. He expressed his disappointment in the cancelation and his hopes to find another platform to execute his vision.

One of Ackles' ideas was to tie The Winchesters to a possible return of Supernatural in the future. He discussed this concept with fellow Supernatural alum Jared Padalecki, who played Sam Winchester. While Ackles didn't give specifics about how the two shows would intertwine, it was clear that there was potential for a crossover. The Winchesters' cancelation adds to the list of failed attempts at expanding the Supernatural universe.

Ghostfacers, a ghost hunting team that appeared in the original series, had its own web series but only lasted one season.

The Supernatural animated series, produced by Warner Bros., saw 22 episodes but had limited involvement from the original cast. Supernatural: Bloodlines, which introduced five crime families battling for control over Chicago, was rejected by critics and fans alike. And Wayward Sisters, a series starring the female characters from Supernatural, was unable to gain traction despite its pilot episode being well-received.

It seems that Supernatural has faced a curse when it comes to spinoff shows. Despite its massive success and dedicated fandom, the series has struggled to find a way to continue its story beyond the original narrative. However, fans of the Winchesters and the Supernatural universe remain hopeful that one day they will get to see their favorite characters in new and exciting adventures.
