ETA: I have already done (in reverse order) Smallville, Stargate: Atlantis, The Fast and the Furious, Oz, Ocean's 11, Buffy the Vampire Slayer, Master & Commander, due South, Pirates of the Caribbean, The Sentinel, and Lord of the Rings. Those can all be found at my Fandoms I Have Loved tag.
ETA2: Allow me to smack my forehead in a painful fashion, because I completely forgot to put on the poll two others that I have in progress: Harry Potter and the DCU. Memo to me: no more posting polls late at night.
TFV, I'd sure like to see you do a Fandoms I Have Loved for:
Angel the Series
Other (and I will say what other fandom in the next question)
You. Yeah, you, the person who said "Other." What did you mean by that, exactly?
