Preliminary Analysis: It was a lackluster night on ABC as 'Shark Tank' (0.5) and '20/20' (0.4) both lost a tenth when compared to their last episodes. The pair was a good bit behind a steady edition of 'WWE Smackdown' (0.6) on Fox. The wrestling program managed to top the night as a result. CBS was stable across the board with 'MacGyver' (0.5), 'Magnum PI' (0.5), and 'Blue Bloods' (0.5), all three matching their week-ago premieres. NBC went with a repeat of 'Weakest Link' (0.4) and a 'Dateline' original (0.4). The CW had the return of 'The Christmas Caroler Challenge' (0.1).
