Just before Supernatural came to an end, there was a legitimate attempt to bring a spinoff. Wayward Sisters would take on two well-known and beloved characters in the Supernatural universe and have them lead a group of younger women as they became Hunters.
Despite a successful backdoor pilot, The CW chose not to go ahead with Wayward Sisters. I stand by my statements back in the day that it was one of the biggest mistakes for the network at the time. However, it will continue to live rent-free in my head.
Now, Supernatural showrunner Andrew Dabb has confirmed the ideas that were behind the spinoff series, making me wish that it happened even more.

Wayward Sisters was going to go back to basics
By the point of Wayward Sisters, Supernatural had moved on from its original premise. At first, the series focused on monsters and urban legends, but by Supernatural season 13, the main focus was on angels and demons. While there were some great storylines to come from this move, it did lose what made Supernatural so amazing to start with.
The all-female spinoff was going to go back to the start. Dabb confirmed with TV Insider that the series would have focused on monsters rather than angels and demons. It was going to head back to where the Winchester brothers started, and it would have helped the series both stand on its own but also remain connected to the original series.
“We wanted to focus on monsters. We wanted focus on kind of back to basics."
After all, it’s not like Jody and Donna were pulled into the Winchesters’ lives because of angels and demons at first. They both came in due to standalone monsters of the week, which was the way many of the beloved supporting characters were originally pulled into the series.
A chance to delve into more cultures and stories
The use of urban legends and monsters is what drew me into Supernatural in the first place. I’ll admit that I wasn’t a Day One fan, but only because it didn’t come to the UK right away. I watched Supernatural season 2, episode 20 first, and the Djinn storyline immediately caught my attention. Okay, a wish-world storyline also did that.
Then I ended up catching the second episode of the series, and again, it was a standalone monster of the week rooted in mythology and urban legends. As I realized what this series was all about, I went back to the start and connected to my past love of urban legends. It reminded me of those stories I’d grown up with, and I got a new take on each one.
Wayward Sisters would have developed a similar vibe by going back to the basics of monsters. It would have offered another chance to delve further into other cultures and understand the things that go bump in the night. After all, there were plenty of cultures with stories that Supernatural only just scratched the surface of or didn’t touch on at all, and Wayward Sisters had a chance to offer us that.
So now I’m even more disappointed that the Supernatural spinoff didn’t happen. Can someone correct CW's wrong, please?
