Fox's 'UFC Fight Night' (0.6) improved significantly from last week's drama repeat and tied for the top program of the night during primetime.
Over on ABC, 'I Want a Dog for Christmas, Charlie Brown' (0.5) had a weak result leading into two hours of 'Ten Days in the Valley' (0.3/0.2). After being off the air since October, the freshman drama fell to new lows. 
NBC had comedy repeats (0.4/0.5), an original 'Dateline' (0.6), and 'SNL Vintage' (0.6). The original 'SNL' at 11:30pm with host Kevin Hart (2.0) was down a tick from last week's episode.
CBS had drama repeats (0.5/0.5) and an original '48 Hours' (0.6).
