Following that controversial ending to the series last year, the horror franchise is getting another entry that is sure to keep fans happy.

US TV network The CW isn't letting go of the 'Supernatural' franchise just yet, as they've announced the series will be getting a prequel all about what happened before Sam and Dean were hunters of the supernatural.

'Supernatural' - the longest-running show at CW - culminated late last year after fifteen seasons, ending with the death of Dean, played by Jensen Ackles. We also saw his brother Sam, played by Jared Padalecki, live out his life in a flash-forward, where he has a son named Dean. Fans of the series widely didn't approve of this ending, citing that Dean died far too easily, and by an unnamed villain.

Well, it seems like redemption could be in order, as the franchise is far from dead and buried. According to Deadline, 'The Winchesters' will be a prequel series about Dean and Sam's parents, John and Mary.

Jensen Ackles will be reprising his role as Dean, but purely as the narrator of the series. He will also act as executive producer alongside his wife, Danneel Ackles, as part of their production company Chaos Machine Productions. Danneel previously appeared on the series as a guest star in the role of Sister Jo.

Jensen said of his involvement in the 'Supernatural' prequel series: "After 'Supernatural' wrapped its 15th season, we knew it wasn’t over. Because like we say in the show, ‘nothing ever really ends, does it?'

"When Danneel and I formed Chaos Machine Productions, we knew the first story we wanted to tell was the story of John and Mary Winchester, or rather the 'Supernatural' origin story. I always felt like my character, Dean, would have wanted to know more about his parents’ relationship and how it came to be. So I love the thought of having him take us on this journey."

'Supernatural' was created by Eric Kripke and holds the title of the longest-running sci-fi series on American broadcast television. Eric is now the showrunner on Amazon Prime's 'The Boys', which is currently filming its third season. Jensen Ackles joins the cast this time around as Soldier Boy.
