USA TODAY - What's worth watching, and what might not be, in prime time on Wednesday.
Christmas in Rockefeller Center| NBC, 8 ET/PT
For the 16th year, NBC builds a musical hour around the lighting of the tree in front of its New York headquarters. This year's guests include Mary J. Blige, Toni Braxton, Mariah Carey, Kelly Clarkson and Jewel.
Astaire/Rogers Marathon | TCM, 8 ET/5 PT
Granted, none of these movies are particularly tied to the season. But if any musical stars can fill you with the joy great talent inspires, they're Fred Astaire and Ginger Rogers. The fun begins with their first pairing, Flying Down to Rio, and continues through The Gay Divorcee (10 ET/7 PT), Roberta (midnight ET/9 PT), Follow the Fleet (2 am ET/11 pm PT) and The Story of Vernon and Irene Castle (4 ET/1 PT). Don't feel bad if you can't dance like they can - neither can anyone else.
Kirstie | TV Land, 10 ET/PT
For its latest star-revival sitcom, TV Land has gathered Kirstie Alley, Rhea Perlman and Michael Richards - veterans of two of the best and best-loved sitcoms of NBC's Must-See TV era - and put them in the hands of Marco Pennette, whose Union Square, Conrad Bloom and Caroline in the City epitomized the loathed time-slot fillers that eventually brought Must-See TV crashing down. What you get is what you'd expect: Fitfully amusing hackwork barely kept afloat by its stars. It's hardly what they deserve, but TV Land is assuming it will be enough - and for some viewers, it may be.
