But nothing is more devastating than its latest foe: Supernatural's own writers.
As I wrote last May, Supernatural's last season was problematic at best despite high-point episodes in "Just My Imagination," "Baby" and "Red Meat." But the final minutes of the season 11 finale in which the Winchesters' beloved mother, whose death is the reason they became hunters, was resurrected; and Sam was shot by a nasty representative of the British Men of Letters, a secret organization dedicated to collecting and archiving information on the paranormal, were promising.
As teased for months, season 12 finds Sam (Jared Padalecki) in the clutches of a British psychopath named Toni Belville, and Dean (Jensen Ackles), with their mother in tow, is determined to track him down. Dean, the consummate badass, even channels his inner Liam Neeson with a "Taken" style threat to Sam's kidnappers and yet it ends with more shark abuse than bad guy thumping. How did it all go so horrifically wrong?
