Question: What the frak! Is Battlestar Galactica ever returning? -- Ken
Ausiello: Good news: A Sci Fi source confirms to me exclusively that the last half of season 4 premieres on Friday, Jan. 16, at 10 p.m. Which, by my calculations, puts the series finale (boo-hoo!) at Friday, March 20. Viewing party at Tim Stack's place, and you're all invited!
