Let me just get it out of the way that I loved every second of Supernatural to date, it had wit, humor, cleverness, action, drama, and of course, the supernatural. All in pretty consistently enjoyable proportions.
This last week, the finale of the most recent season aired. There be spoilers comin' so avert yer eyes if you've not seen it and you want to be surprised.
During the previous season the brothers unwittingly kicked off the apocalypse, and set Lucifer free from his prison. This last season mostly dealt with them trying to thwart the full on apocalypse, and trying to find a way to kill the devil without having to wipe out half the planet. It's further revealed that the brothers are both destined to be the vessels for Lucifer and Michael to possess and do battle to determine who wins. The eventual scheme that could succeed is to collect a ring from each of the four horseman, which when used together, form the key to the prison where Lucifer was confined, Sam lures him in, says "use me like the meat puppet I am" and then hopefully has enough control left of himself to jump into the trap.
After a false start, this plan eventually succeeds, although Sam and Satan aren't the only ones trapped, Michael gets trapped as well (using the stand in vessel of Adam, the recently discovered, murdered and resurrected, bastard Winchester brother). Apocalypse averted, Castiel, by far my favorite character on the show, shows up with newly acquired super angel powers, and states that he's going to ascend to Heaven and set things in order, now that Michael's not around to be top dog. Dean makes good on his last promise to Sam, which is to hook up with a woman he'd left behind, and make a normal life for himself.
I like this as an end to the series, there's a monologue from the prophet, a fiction author named Chuck who's published the Winchesters' life stories as a series of urban fantasy novels, where he says that endings are hard, you're supposed to bring as many of your stories to a close, and somehow make it all mean something. This story doesn't really have a meaning, other than the Winchesters making a choice, for family over death. I don't know how much I agree with that, but I don't really need the ending to mean anything, other than two brothers deciding that the world shouldn't end, and doing whatever it takes to make that happen, even if that means locking one of them up in a vault with Lucifer for eternity, or long enough that it might as well be.
Sadly, the story doesn't end here, it turns out that they've been renewed for another season, despite a couple of interviews I've read with the creators where they more or less said that this was it, the story is over. There are a few more additions to the end of the finale that leave it open for another season.
One, the prophet, Chuck, after finishing the story, lifts his hands from the keyboard, and just disappears in a puff of smoke, leading me to believe that he wasn't just a prophet, but God himself, either knowingly, or unknowingly. God's been absent for the entire series, there were a few inexplicable miracles that are blamed on God's will, but there's never really much of a confirmation, at one point, Castiel even sets out to find God, since that's the only way to avert the end of days.
Two, as Dean enters the home of his lost love, to have a beer, the camera pans back to show Sam standing under a tree watching him. Did God just snap his omnipotent fingers in order to reward Sam? Is the Devil free again? Maybe Sam's just capable of seeing his brother be happy as a reward?
The bottom line is that the story is now set to go on, when it really felt finished, and let's face it, how is anything going to seem tense and like something important's at risk after we've already faced the forces of Heaven and Hell, and averted the apocalypse? I suppose I'll give it a try, but I dunno, I kind of feel like I should just not watch the next season, since I'm already so happy with how the story ended.
