Well, what can I say?
This season felt pretty... bleak, I guess is the best word.
Maybe even a little bit uninspired.
I guess I'm way too late for this discussion, but I feel after Kripke's run, and the shows supposed intended ending (though I remember this just being a rumor back then, correct me if I'm wrong.), they've gone a little overboard with the war for heaven stuff.
I liked the 6th season dealing with the effects of Lucifer's cage on Sam, but pretty much everything else was where they started to descent into madness basically.

t:
Season 7 was somehow pretty cool with all it's cheesiness, the Leviathan story was ridiculous but fun. And the following purgatory/tablet stuff in season 8 was also interesting. I especially liked Ty Olsson/Benny, he was a really great addition to the cast and I was really bummed out they killed him off. (At least that's how I remember it, once again: correct me if I'm wrong.) And the bunker was a great idea after Bobby's house was burned down.
As you can see, I pretty much liked everything besides the Angel stories.
This worked great in season 4/5, but now they just seem boring.
The same thing applies to the war for Hell, even though I liked that they showed us more of Crowley's ambitions.
That being said, Singer and Carver lost me halfway through the season, because I just got so fed up with the whole Metatron/Angel/Castiel/Angel Army-thingy. I watched the last few episodes I missed over the past couple of days, basically just to get it over with, and it almost felt like a chore except for the last 2 episodes.
The conclusion of the season was good, not overly great, but it felt right.
Dean [BLACKOUT]becoming a demon[/BLACKOUT] was kinda predictable at some point, but not a bad decision.
All in all, and I'm not trying to be a whiner here, I got to say that to me the show has lost much of it's original appeal to me, which is kinda sad.
But, oh well, who actually cares? It's for the most part still a fun show, and will still be a weekly thing for me to watch this fall.
I'm just hoping they bring it all to an end with the next season.
Maybe bring back Jeffrey Dean Morgan and Jim Beaver for one or two episodes and I'm happy. I wanna see the "original" three Winchesters and Bobby fighting side by side for the shows finale.
