Christmas in Rockefeller Center - Season 22

A selective critical checklist of notable Wednesday TV:

The Moodys (9/8c, Fox): Think of this short-run comedy as an acerbic antidote to the heaping helpings of holiday schmaltz so prevalent elsewhere. This decidedly offbeat limited series — six episodes, airing back-to-back tonight, then again next Monday and Tuesday — stars Denis Leary and Elizabeth Perkins as the parents of a barely functional brood of grown children who gather for a harried, rather than entirely merry, Christmas. It opens with mom shooting the head off a mantlepiece Santa, then backtracks several days to show how they got to this breaking point. (See the full review.)

Fox's offbeat short-run comedy about a suburban family falling apart at yuletide is an antidote to TV's prevailing holiday schmaltz.

Also going a bit darker than the usual holiday fare: Freeform's Ghosting: The Spirit of Christmas (9/8c), an odd twist on a rom-com in which Jess (The Bold Type's Aisha Dee) dies in a car accident on the way home from a great first date with Ben (Insecure's Kendrick Sampson), whom she inadvertently "ghosts" from the other side. The only person who can still see and hear Jess is her BFF Kara (Orange Is the New Black's Kimiko Glenn), who must figure out how to get her unstuck from Earth — and Ben.

Current contestant Dan Spilo was a common factor in the women's discussions this week.

Survivor (8/7c, CBS): Typically one of the most emotional episodes of any season, the family visit is likely to bring many of the remaining contestants some much-needed joy — although it could also fuel resentments depending on who gets to take advantage of an extended stay. The timing is also tricky, as this is happening just as alliances continue to shift among the tribe.
