I am currently filled with very little but yay for Prison Break (the one exception being my dislike of the whittling down of the female roles from last year). I'm excited and interested about what'll be happening starting January 22. But while I adore the show, I find that I don't feel very fannish about it -- not the way I do about Supernatural (Numb3rs, the other 'brothers' show, also fills me with a non-fannish level of glee). I just want to... watch and enjoy. House, Boston Legal, and Bones are similarly non-fannish sources of delight for me.
Torchwood, on the other hand, I feel very fannish about (along with Doctor Who, Battlestar Galactica, the Stargates, Supernatural, and Smallville). ( spoilers for Torchwood 1x07 -- Greeks Bearing Gifts )
Apparently there is going to be one episode of Supernatural in all of December. On the 7th, I think. I'm both looking forward to it and yet also sad about the three weeks of December in which there will be no Supernatural at all. Woe!
