the show used to have the hunting things saving people (save the world theme) and I feel in the past two Carver seasons, it’s more about the brothers dynamic, which while interesting, would be like all domestic scenes of Superheroes and none of the derring-do. We also had a possibility of richness to the world with a growing circle of friends that was shredded in season nine for cheap thrills. The bunker family, Dean and Sam, Cas, Kevin, Charlie, was very compelling to fans. At least we had fun with that in fic and art.
The Demon Dean story (to me) is not as compelling as save Dean from going to Hell, save Dean from being Michael’s vessel storylines, to make him demonic means he failed, and his friends failed him, and the effort of nine years feels wasted. (and to top it off, it wasn’t because he was doing the right thing, the writers gave Dean selfish motivations) and I won’t be surprised if it’s short-lived, three or four episodes, and then we get 3/4 of a season of yet more guilt and self blame for the older Winchester.
So the promise of new characters doesn’t thrill me (they’ll all die) both hellgate closings and angels falling to earth concepts fizzled, and poor Castiel (even after Misha was upgraded to regular) was given no character arc, only pain and sidelining until he was needed. It’s more than depressing when a side character (Crowley) gets more development than any of the leads. So many episodes ideas cribbed from previous seasons, the show could do with a writer overhaul.
Going into season ten, I feel no urgency, no concern, it’s no longer about saving the world, I know that even if I grouse (and stop watching, and I’ve been there since the pilot) it won’t make a difference because ratings are going gangbusters, sadly that’s not for stellar writing, that’s all due to the fanbase, so remember to remind those guys how they can keep going another season, it’s all because of you.
