11 seasons? Jesus. I pretty much stopped watching after season 3, lol. I guess it must have something of merit to reach 11 seasons.
Don't forget Crowley. I still enjoy the series but I don't see it lasting much longer. Eric Kripke(?) only wanted to do 5 seasons and part of me wishes it had stopped there. Doesn't have the same feel as the first seasons. Having said that I can understand why they'd take a new direction, it'd be tough to maintain the original premise for so long, something would have to change. I'll still watch it, I'll still (hopefully) enjoy it.
