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.

It sounds like one of those old jokes: A vampire, a werewolf and a ghost move into a house...

But it's no joke, it's the premise of "Being Human" (Syfy, 9 tonight), a not original, but still likable series about a vampire, a werewolf and a ghost living together.

Based on a British series (that's supposed to pop up on BBC America later this year, making for awkward comparisons), "Being Human" is set in Boston, where the pasty vampire Aiden (Sam Witwer) and werewolf Josh (Sam Huntington) work at a hospital and struggle to fight their monstrous impulses. For Aiden, that makes drinking blood from the blood bank; for Josh, it means going deep into the woods when the full moon rises so, perhaps, only a random deer will get savaged.

The Middle/Better With You/Modern Family/Cougar Town (8pm, ABC) - ABC comedies all have special Halloween episodes tonight. On "The Middle," Frankie and Mike are invited to an adult Halloween party in the neighborhood. On "Better With You" (just picked up for a full season) Maddie is upset that her birthday, which falls on Halloween, is always overshadowed, so Mia and Casey offter to throw her a party. On "Modern Family," Claire's elaborate Halloween plans (evidence at lef) depend on the rest of the family's help with trick-or-treaters, and the holiday conjures up terrible memories for Cameron. On "Cougar Town," Jules reluctantly dons a costume for Halloween when her father (Ken Jenkins, "Scrubs") comes to visit on his favorite holiday.

Undercovers (8pm, NBC) - This show falls under the "watch it while you can" category -- most are expecting it get axed any day now. But for now, you can watch the Blooms try to recover a  painting that's hiding a formula for a biological weapon. Or not.

Criminal Minds (9pm, CBS) - In an especially creepy episode, the team travels to Detroit to catch a killer who, for the past three years, strikes on "Devil's Night," the city's pre-Halloween celebration.

I'd Do Anything (9pm, BBC America) - The premiere of a new series in which hundreds of aspiring stage actors attend open casting calls in London for the lead roles in Andrew Lloyd Webber's West End revival of "Oliver!"

Daily Show with Jon Stewart (11pm, Comedy Central) - Stewart is doing his show from DC this week, and tonight's guest is President Barack Obama.

By its barest description, "Luther" (BBC America, 10 p.m. Sundays) sounds like you've seen it a thousand times.

It's about a troubled brilliant cop (played by Idris Elba aka Stringer Bell on "The Wire") whose questionable tactics give him the right results with murky morality. But "Luther" offers so much more than that description. This is an intense, complex, creepy ride.

When we meet John Luther, he's chasing a man who has killed several children. He's got him cornered, and in forcing him to give the location of his latest victim, Luther makes a choice that provides the subtext for nearly everything that happens in the six-part series. (I've seen three and I already want more than six.)

My Boys marathon (12:30pm, TBS) - In advance of the Season 4 premiere (tomorrow night), TBS is showing a marathon of the best episodes of their original comedy series, "My Boys." Today's 3-hour marathon features some of the best episodes of Season 3.

Dogs vs. Cats (8pm, Animal Planet) - A debate as old as time itself: which species is better, dogs or cats? I know where I come down (meow). I'm betting in the end they won't actually pick a side, but should be a fun show.

Persons Unknown (8pm, NBC) - Joe confesses to Janet what he knows about the kidnappers, then Blackham and Erika make a plan to use Joe in an escape attempt.

Being Human (10pm, BBC America) - Season 2 opens with the vampire society in complete disarray after Herrick's death, and George feels like a changed man after killing him. That is, until he discovers a horrible truth about Nina.
