As the two-hour series finale of Battlestar Galactica approaches this Friday, SciFi Channel brings us “The Last Frakkin’ Special” tonight (10 PM ET/PT and rebroadcast a lot this week). Hollywood.com puts it on the Do It Today notice. Want to find Cylons in your midst? Get the Cylon Detector iPhone / iPod Touch app. It’ll work better than Baltar’s blood screening. and Remember, the final episode of BSG: “Daybreak, Part 2” this Friday night, 9 PM ET/PT.
