The CW's "Supernatural" ended after 15 record-breaking seasons, with the demon-hunting siblings Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) both ending up in Heaven after it was all said and done. Of course, it was only a matter of time until the network tried to capitalize on the success of the hit horror show, and the prequel series, "The Winchesters," was born -- only to be canceled after one season.

"The Winchesters" switches the action to the '70s and follows Mary Campbell (Meg Donnelly) and John Winchester (Drake Rodger) -- aka Sam and Dean's parents -- as they fight all manner of creatures and crush on each other. They are also joined by a Scooby Gang-esque group of monster hunters who help them out along the way, making for a fun, diverse, and action-packed viewing experience. Sadly, the gang's adventures weren't destined to last, no matter how much they enriched the "Supernatural" universe.
