I did like how they were able to mix in a lot of "monster of the week" episodes, though.
I wonder if a series finale story arc could involve the Winchesters finding God (literally, not spiritually). The angels keep implying that God is missing.
I caught a re-run on TNT last week where the outcast angel Anna said that there were only four angels she knew of that have actually seen God. It was just speculation on my part, but if they are going to wrap the show, finding God has to be the end game, you would think. Just don't let it turn into a Contact type moment where they find God, and he turns out to be Jeffery Dean Morgan.
And I agree about the Leviathan storyline. Least interesting baddies yet. But, Castiel pretty much wiped the angels off this plane of existence, and Crowley has his minions laying low. We'll see how it goes. (And wasn't it implied by Crowley after Dick was killed that the Leviathans would still be around, but nowhere as powerful? I can't quite recall....)
