I haven't owned a TV in 6 years now. Any time I try to watch any of these shows I get bored within 5-7 minutes. I'm usually walking away by the first commercial break.
ive never owned a tv (or more correctly, never purchased (or "borrowed") tv service. Best ive ever had was very very very snowy (think polar bear in a snowstorm) reception for the olympics once via rabbit ears.
But internets now. I still dont watch much tv, but ive seen all of Game of Thrones, first two seasons of battlestar, first two seasons of 24, 3 seasons of eureka, and a few other small things here or there.
Most recently, the Blood and Chrome miniseries for battlestar, which was actually pretty awesome. I wish scifi had picked it up, it was good. Way better than caprica.
