What We Do in the Shadows

A selective critical checklist of notable Wednesday TV:

What We Do in the Shadows (10/9c, FX): Time to get familiar again with the funniest TV vampires since Grandpa Munster, in FX's adaptation of the cult movie, now in its second season of supernatural hilarity. The hapless Staten Island vamps are under siege by assassins from the Vampire Council, but only Guillermo (Harvey Guillén), the underappreciated "familiar" – i.e., servant/would-be vampire in training — is aware of the threat, keeping his dim-witted master Nandor (Kayvan Novak) and married ghouls Nadja (Natasia Demetriou) and Laszlo (Matt Berry) in the dark. Adding to poor Guillermo's woes: an arrogant new familiar (Haley Joel Osment) who does none of the work but seeks all of the credit. In the second episode (10:30/9:30c), Nadja conducts a séance to rid their rotting mansion of ghosts, but only makes matters worse by conjuring new and familiar spirits, all needing to tend to unfinished business before they can move on. Not since Dark Shadows have I enjoyed the company of the undead more.

The gang deals with a spectral infestation in Wednesday's two episodes.

Mrs. America (streaming on FX on Hulu): Women rule in a thrillingly acted limited series that recreates the 1970s battle over ratification of the Equal Rights Amendment. Launching with three episodes (the remaining six episodes drop weekly), Mrs. America stars Cate Blanchett, chillingly poised as politically connected conservative firebrand Phyllis Schlafly. Her opposition is a who's-who of marvelously embodied icons: Tracey Ullman as Betty Friedan, Rose Byrne as Gloria Steinem, Margo Martindale as Bella Abzug and Uzo Abuda as pioneering African-American presidential candidate Shirley Chisholm. They'll need a bigger Emmy ballot for this one. (See the full review.)

Chicago Med/Fire/P.D. (8/7c, NBC): Dick Wolf's "One Chicago" triumvirate of procedurals grinds to a sudden halt with tonight's originals, the last completed before the outbreak halted production. In Med, Crockett (Dominic Rains) is paid an unwelcome visit by New Orleans detectives snooping into his past. On Fire, Lt. Severide (Taylor Kinney) works overtime to help a fellow crew member who's injured on a call. And P.D. wraps with Atwater (LaRoyce Hawkins) going undercover in a gun-trafficking ring, only to discover someone he knows also working incognito.

In revolt, each of the gang sings from the pop/rock musical with songs reflecting their inner angst.

Inside Wednesday TV: Get out the tissues. It's time for the family visits for the remaining castaways on CBS's Survivor: Winners at War (8/7c), always an emotional high point of any season.

Regis's daughter JJ is the comedy's co-creator and executive producer, so it's old home week… HGTV's ubiquitous Jonathan and Drew Scott are back for a new season of Property Brothers: Forever Home (9/8c), turning family homes into places no one would ever want to leave… On a somewhat smaller yet still epic scale, Fox's LEGO Masters (9/8c) challenges its final three teams to make their greatest builds yet to declare a winner in the season finale.
