In Chuck we trust! Both me and my man are huuuuge Supernatural fans, and haven't missed one yet. The new season is getting pretty darn interesting, by the way.
I usually watch the entire season when it's available on Netflix, so I can't wait for the new episodes. The mythology of this show went to hell (pun intended) after Season 5, but for me it remains mandatory watching because of the two leads. The Winchester brothers are fantastic.
