Hulu has been playing a "last week to watch the first episode of the season" ad with a clip of Sam torturing a woman (who is presumably possessed by a demon) and asking "Where is my brother?" all urgent-like. Which on the one hand, kudos to whoever chose the clip because that's it, that's the show. But on the other [evil] hand, that's it, that's the show. I feel like if I knew for sure that this was the last season, then I could keep watching, but if there's more, I'm not sure I can make it. And the fact that I'm thinking about it in those terms is sort of an answer to the "should I keep watching?" question in and of itself.
