Supernatural: Every Season Ranked Worst To Best

15. Season Twelve

There's only one thing worse than a season of TV being bad, and that's it being forgettable. Supernatural's twelfth outing is the show's dullest and most uninspired affair. It's not necessarily bad, but it is lacking the punch the rest of the show conjured up with its stories. It's just kind of there, going through the motions but doing little to justify its existence.

Despite always being a lot of fun to watch, Lucifer's presence in season twelve sees him become stilted and boring, and the British Men of Letters remain some of the show's most unthreatening and pointless villains. Even Castiel seems left out in the cold, limiting his importance in the story until the sudden twist of the finale.

All that aside, there are some good spots, particularly in the return of the brothers' mother, Mary, who adds a solid level of drama when interacting with Sam and Dean. Other than this addition and some typically strong performances from the main cast, season twelve still stands as the most mismatched season of the show.
