If your pop culture knowledge has a big gap in the shape of 'Battlestar Galactica,' you can join me today in watching the repeats on BBC America.

The network has acquired the complete run of the series and it all begins today. All reports I've read say the series starts at 7 p.m., but there's a two-hour 5 p.m. episode that various BSG geeks tell me we should also catch. So I'm taping all four hours tonight. Join me!
 

I have heard such amazing things about this series, I hope my expectations aren't set too high.

I didn't watch "Battlestar Galactica" yet I was intrigued by the pilot of "Caprica," the prequel to that show that airs tonight on Syfy at 9.

Of course, that might be why. For those familiar with this world, it might seem like a retread or simply forced.

Set 58 years earlier than BG, the show focuses on two fathers, Daniel Graystone (Eric Stoltz), a computer genius specializing in artificial intelligence, and Joseph Adama (Esai Morales), a prominent attorney. (Frakin', by the way, is the expletive of choice on "Caprica.")

Hope for Haiti (8pm) - This is airing on pretty much every network in the world. Read more about the program and those scheduled to perform.

Caprica (9pm, SyFy) - The premiere of a new show which serves as a prequel to Syfy's acclaimed hit, "Battlestar Galactica." "Caprica" is set more than 50 years prior to BSG and tonight's episode focuses on a tragedy that impacts the Graystone and Adama families. Eric Stoltz and Esai Morales (left) star. Our review of "Caprica."

Spartacus: Blood and Sand (10pm, Starz) - Lucy Lawless is one of the stars of this new action drama about a rebellious Roman slave played by Andy Whitfield. Tonight, Spartacus and his fellow fighters align themselves with Rome to protect their homeland, but become disenchanted with Rome when their village is invaded by barbarians.

Late Night with Conan O'Brien (11:35pm, NBC) - It's Conan O'Brien's final night hosting "The Tonight Show" for those bozos at NBC, and considering some of his other antics this week, there's no telling what he'll do. It'll be worth checking out. His final guests are scheduled to be Tom Hanks (who gave O'Brien his much-despised nickname "Coco"), Will Ferrell (who was his first guest on the show), and Neil Young.

SyFy's "Battlestar Galactica" was voted Television Program of the Year at the Television Critics Awards Saturday night.

HBO's "True Blood" was named Best New Show, AMC's "Mad Men" was named Best Drama, and Bryan Cranston won Best Actor for AMC's "Breaking Bad."
