1) “What We Do in the Shadows” season-openers, 10, 10:34 and 11:09 p.m., FX. This weird – and weirdly funny – show has gradually been noticed, with three best-comedy Emmy nominations in five years. Now its final season starts with these cozy vampires (Nadja is shown here) waking Jerry The Vampire, wh has a key question: If vampires are secret, why is a human camera crew there? No one can remember.
2) “NCIS: Origins,” 10 p.m., CBS. For Franks (Gibbs’ boss and mentor), it’s a rough time. An investigation takes him to a modern (for 1991) mall; this is not his natural turf. Also, Gibbs’ father, who has anger issues, barges in.
3) “Poppa’s House” debut, 8:30 p.m., CBS. Here’s the night’s biggest mystery: How could Damon Wayans – once part of the sharp-witted “In Living Color” – star in such a witless comedy? He plays a radio host, with a disapproving co-host and a pleasant son. The characters are exaggerated; the jokes are flat and forced.
4) “Whitstable Pearl” season-opener, www.acorn.tv. In a gentle, coastal setting, Pearl is both a restaurant owner and a private eye. The characters are likable; the weekly stories are varied. This first one is OK, the next two are terrific; then “Pearl” stumbles for two weeks, before an excellent season-finale. Overall, it’s worth trying for a couple weeks.
5) ALSO: There’s a batch of 8 p.m. choices. CBS has the “Neighborhood” season-opener. NBC has “The Voice,” ABC has “Celebrity Wheel of Fortune,” Fox has “9-1-1: Lone Star,” with a horse crashing into a brewery. (That never seems to happen in Bud commercials.) And CW has “Superman & Lois,” which last week saw the dead Superman open his eyes.
