If you’re a Battlestar Galactica fan, you’re probably all worked up in a lather over tonight’s resumption of the final season on SciFi. But are you really a fan? I mean, really??? Are you wearing a Cylon helmet? Have you maxed out your frak-ing credit cards on BSG attire and swag? Have you signed up for a battlestargalactica.com e-mail address? Have you watched the Starbuck music video, for frak’s sake?
