* BONNIE & CLYDE. 9 p.m. Sunday and Monday, A&E/Lifetime/History.
History, the bloodier the better, should probably be the new motto for the A&E Networks. After the History Channel reaped record ratings for "Hatfields & McCoys," execs were confident enough in the appeal of Lifetime's two-night "Bonnie & Clyde" to splash that doomed and deadly couple, played by Holliday Grainger ("The Borgias") and Emile Hirsch ("Into the Wild"), onto sister networks History and A&E, too. Stylish, but not for the squeamish.
* MASTERPIECE CLASSIC: DOWNTON ABBEY. 8 p.m. Sunday, WHYY12.
Don't get too excited - Season 4 doesn't launch in the U.S. until Jan. 5. But if you're behind - or have forgotten some of the less-tragic moments of Season 3 - it's being rerun this month, with two episodes each Sunday.
* GUESS WHO'S COMING TO CHRISTMAS? 7 p.m. Sunday, Up.
So many cheesy holiday movies, so little time. I think only one, though, features both 98 Degrees veteran Drew Lachey - as a stuck-up rocker whose manager sticks him with an impossibly wholesome family for Christmas - and something called "Spam sushi." Oh, and there are llamas. Enjoy in your ugliest holiday sweater.
* TRAPPED IN THE CLOSET. 5:15 p.m. Saturday, IFC.
With R. Kelly's weirdly hypnotic hip-hop soap scheduled to resume on IFC in 2014, the network's holding a 33-episode marathon. It won't take as long as that sounds: Most installments are only a few minutes long.
