I got off the bandwagon when they did the "Lets travel back in time to learn everything" cliche. I've been considering trying again, but I just don't know, for me it seems to have fallen into a loop. I like one season, only like a few episodes of the next season, like the the next season, and only like a few episodes of the next season.

I've started watching Being Human(http://www.sidereel.com/Being_Human) recently and so far it looks like a good substitute until I get back into SPN, if I do.
