SPECIAL PREMIERE: ABC’s inferior but still watchable version of The Great British Bake Off returns, with more holiday recipes and lighthearted competition. Sadly, don’t expect any recipes involving razzleberry dressing…
BBC America, 9:00 p.m. ET
SPECIAL PREMIERE: The new season of Doctor Who begins next year – January 2, so there’s not that long a wait. Meanwhile, there’s this Boxing Day special, a sort of Doctor Who holiday tradition. A stand-alone episode bridging the gap between seasons… and followed, this year, by another of the series’ excavational specials, using animation and new vocal tracks to supplement and complete a “lost episode.”
