Lost, Fringe, even Smallville... This week saw the season finales of all, bringing another year of television greatness (and less than greatness) to a close. But which finale brought insane, nailbiting "must-see-what-happens-next" feelings the most?

Please note: Yes, I've probably forgotten a show or two, but things like Doctor Who or Battlestar Galactica aren't included on purpose; we're really asking about the finales on the main broadcast networks over the last month. And if someone wants to make the case that stylistic similarities between the end of House and Fringe really mean that Greg House is just traveling between alternate Earths, we'll happily take that as an excuse to finally claim that the show really is sci-fi, honest.
