Battlestar Galactica (2003-2009)
It is the end of an era. Not since Buffy the Vampire Slayer (1997-2003) ended have I been so eagerly anticipating the series finale for a TV show. I will miss these characters, this world and this story dearly: what do I do in a world without a strong-willed Roslin, a rambunctious and yet vulnerable Starbuck, and a seductive and serpentine Six? Here's hoping BSG ends with a bang and not a whimper tonight. So say we all!
