Supernatural Returns For Its Fifteenth and Final Season

Entering its fifteenth and final season, Supernatural has enjoyed such a long run that it's outlasted its original network (The WB), but also every other show that was a part of The CW's inaugural lineup. All the while, the Winchester Brothers — played by Jared Padalecki and Jensen Ackles — have been reliably chasing down ghosts, goblins, and other monsters of the night. In last year's finale, the brothers managed to anger God — it's a long story — who decided to end the world by unleashing all the demons in Hell. All of which is to say, the Winchesters definitely won't be phoning in their last season.
