The tidbit for December 2 is a short story.
I suspect that the powers that be were shooting for a feel like one of the old Doctor Who annuals (I haven't seen a recent one) - Tardis lands, picks up a new companion, goes off somewhere else, meets a new monster, quick bit of tension and the monster turns out to be peaceful. Hoo-rah! The essence of what some people think the show is about distilled down to three pages.
And it's Christmassy, in that it's all wintery. (and topical in that it's all global warmingy)
