with a new show when:
You can’t stop reading people’s reactions to the season finale a week after it’s aired.
You start an internal clock of sorts, counting down the days for a potential season 2.
You say frak instead of the more appropriate fuck or frell.
You wish you were Starbuck (drag if more appropriate).
You threaten the Sci-fi network by standing outside their offices and perform a horrible rendition of the new Battlestar Galactica theme song (UK version) if they refuse to greenlight a second season.
