TONIGHT'S MUST-SEE

"Battlestar Galactica," 7, 8 p.m., NBC. Next Friday, this terrific show starts its second season on cable's Sci-Fi Channel. Tonight NBC offers a quick chance to catch up on the final episodes of the first season; it reruns one episode at 7 p.m. and the sensational, two-hour cliffhanger at 8. First a recap: The Cylons control most of the galaxy. A rag-tag fleet of humans is on the run under the tenuous military-civilian rule of Commander William Adama and President Laura Roslin. The Cylons, devious and robotic, can create humanlike creatures to go undercover. That includes two Sharons — one on board, the other stranded on a Cylon-controlled planet. Another Cylon — the gorgeous No. 6 — has infiltrated the mind of Dr. Gaius Baltar, the evil scientist who is vice president. Heroes include Capt. Lee "Apollo" Adama (the commander's son) and Lt. Kara "Starbuck" Thrace. Huge events are coming up for Starbuck, including an ill-advised one-night stand, a dangerous mission and a fierce fight. There's much more, including Roslin's vision of a bountiful planet. Then comes the cliffhanger. This is first-rate fantasy.
