ROCK CENTER WITH BRIAN WILLIAMS
NBC, 10:00 p.m. ET
Perhaps because NBC has announced plans to shift this newsmagazine to a less popular Friday night time slot next year, Rock Center is filling tonight's show with a rerun. But it's a good one -- a recap of President Obama's successful targeting of Osama bin Laden. With the film Zero Dark Thirty about to hit theaters nationwide, it's a well-timed primer. And the Julian Fellows Downton Abbey feature I wrote about earlier is available on the Rock Center website.
