Watchable Dec. 6 to 12, 2021

SHOW OF THE WEEK: The Expanse (Dec. 10, Amazon Prime Video)

If you’re going to go out, might as well be with a bang than a whimper, which is how “The Expanse” does it in its supposed final season.

There’s been speculation the sci-fi drama could go on were it to find yet another host network — it was rescued by Amazon after Syfy’s cancellation at the end of its third season — but if this six-episode Season 6 is all viewers get, it’s acquitted itself well.

As it begins, we’re dropped into the middle of the war between the Free Navy — the renegade group of Belters led by Marco Inaros (Keon Alexander, rocking a serious man bun) — Earth and Mars.

Earth has found a way to destroy the asteroids with which Inaros has been bombarding the planet, killing millions, but at the expense of keeping its ships pinned down and unable to pursue Marcos.

I don’t think it’s a spoiler to say that situation won’t last and that when the fight comes, the Rocinante is at the heart of it.

Dedicated fans will be gratified to see Holden (Steven Strait), Naomi (Dominique Tipper) and Amos (Wes Chatham) reunited aboard the Roci.

Though Alex is gone — killed off at the end of Season 5 after actor Cas Anvar was accused of sexual misconduct — he’s not forgotten, with his crew mates making it clear that he’s missed.

And that’s kind of important because without the bonds between these characters, “The Expanse” wouldn’t be the show that it is, one that its fans love so passionately they refused to let it die back in 2018.

It’s also a strength of this season that time is taken amid the action to check in with the characters and their relationships. Part of that involves grappling with the guilt they carry, whether it’s Naomi’s over the son she chose to leave with the Free Navy or Clarissa Mao’s (Nadine Nicole) over the many deaths she’s caused.

It’s a point worth making that violence has a spiritual and psychological as well as a physical cost.

“The Expanse” continues to give ample attention and agency to its female characters, not only Naomi and Clarissa but Bobbie Draper (Frankie Adams), Camina Drummer (Cara Gee) and the indomitable Chrisjen Avasarala (Shohreh Aghdashloo).

The downside is that, with just six episodes, plot developments really speed along, especially in the finale. There are also some loose ends, including an arc on the planet Laconia that gets a fair bit of attention but not a conclusion, as well as a key character we see abandoning the final battle and flying off solo to parts unknown.

But that’s also good news if “The Expanse” does get more seasons since it provides some built-in starting points. If this is all we get, though, it leaves viewers and the characters they’ve cared so deeply about in a good place.

Short Takes

Landscapers (Dec. 6, 9 p.m., HBO/Crave)

One question nags at you when you begin to watch this miniseries: how could the innocuous-looking, somewhat dotty couple it portrays have murdered her parents, buried them in the backyard, and lived off their pensions and other money for 15 years? I only had time to screen one of the four episodes of “Landscapers,” but I presume that becomes clearer in the other three. Olivia Colman (“Broadchurch,” “The Crown”) and David Thewlis (“Harry Potter,” “Fargo”) play Susan and Christopher Edwards, a real-life British couple serving life sentences for the murders of  William and Patricia Wycherley in 1998. This isn’t the kind of crime procedural we’re used to seeing. It blends scenes of the Edwards, broke and living in France as the series opens, and of the Nottingham detectives who are on their trail with fantasy sequences involving actor Gary Cooper, with whom Susan is obsessed, and behind-the-scenes glimpses of the miniseries production. In real life, the couple spent most of the money they stole from her parents on memorabilia of Cooper and other Hollywood stars. As played by Colman, Susan seems to have a tenuous grasp on reality but an unshakeable bond with devoted husband Christopher, which makes this a love story as well as a crime one.

Welcome to Earth (Dec. 8, Disney Plus)

There is a whole subgenre of TV shows about the wonders of the planet, but this one has something the rest don’t have: charismatic actor Will Smith as a guide. Smith, who’s got to be one of the most popular actors in the world, joins explorers on a tour of what Disney calls “some of the most thrilling spectacles on the planet.” In the first episode, which I screened, that involves climbing into a tiny submarine and plunging more than 3,000 feet below the surface of the Atlantic Ocean — marine biologist Diva Amon says fewer people have been to the bottom of the ocean than have gone into space. Smith gets to see wondrous bioluminescent creatures as the sub hovers a few inches above the sea bed. And yes, it would be terrifying to know the only thing protecting you from death at the bottom of the ocean is about six inches of plastic. The episode breaks off from Smith’s adventure to profile other wonders that can only be seen in the dark, including a moonbow over the Iquazu Falls in Brazil. But as fascinating as those other sights are, I suspect viewers will be most engaged when Smith is onscreen. The show doesn’t have an overt environmental message, at least not in the episode I saw, but it’s impossible to watch this sort of program and not think of the threat to the Earth and everything on it posed by climate change.

Odds and Ends

I’m not gonna lie, “And Just Like That. . .” (Dec. 9, Crave) is the show I’m most curious about this week. As a devoted “Sex and the City” viewer I want to know if this sequel measures up, especially with the absence of Kim Cattrall. I didn’t get an advance look, however, so I’ll just have to wait and see.

Crave also has the premiere of “1 Queen 5 Queers” (Dec. 9), which stars “Canada’s Drag Race” judge Brooke Lynn Hytes, leading panel discussions on sex, relationships, pop culture and other issues of interest to the LGBTQ community.

Global TV has a sneak peek episode of “Abbott Elementary” (Dec. 7, 7:30 p.m.), an ABC mockumentary comedy about teachers in a Philadelphia grade school.

YouTube has the third instalment of “Bear Witness, Take Action” (Dec. 6, 7, 8), a series of short films made from the perspective of Black creators and hosted by Common and Keke Palmer.

Netflix’s offerings include the animation-live action hybrid comedy “Saturday Morning All Star Hits” (Dec. 10) starring Kyle Mooney of “Saturday Night Live” in a parody of 1980s and ’90s Saturday morning TV; “Voir” (Dec. 6), a series of visual essays celebrating cinema; the reality series “Twentysomethings: Austin” (Dec. 10); the comedy special “Nicole Byer: BBW (Big Beautiful Weirdo)” (Dec. 6) and a whack of other stuff.

If you like fish-out-of-water and/or redemption comedies, Acorn has the series “Under the Vines” (Dec. 6), in which a man bequeaths a failing New Zealand vineyard to his stepdaughter, a broke Australian socialite (Rebecca Gibney), and his nephew, a disgraced British lawyer (Charles Edwards, “The Crown”). Naturally, they make the illogical decision to give it a go.
