Tune in Tonight: Killers on the prowl and Robert Durst, too!

There’s blood in the watering hole. Again! The new nature documentary series “Predator v Prey” (8 p.m. Saturday, BBC America and AMC+, TV-PG) returns to familiar scenes of slaughter in the heart of Africa, where apex predators like lions, cheetahs and crocodiles feast on zebras, antelope and gazelles.

There are plenty of scenes of deadly ambush, chase and killing, but the emphasis here is on the skills and strategies that have evolved over millennia to give these hunters the upper hand — or paw, if you will. On the other side, their victims have also been endowed by evolution with strategies of their own, making these hunting dramas a master class in escape and survival.

Every generation gets the nature series it deserves. The visual effects here are heavy on CGI graphics, all the better to discuss each specimen in detail.

Time was, predators were discussed in military terms, their aggressive actions likened to merciless armies. It’s not a mystery why the Nazi army named their tanks after tigers or dubbed whole divisions as would-be panthers. With memories (or interest) in that war receding, “Predator v Prey” unfolds like a true-crime drama. The emphasis here is on forensics. The narration by Howard Charles (“Whitstable Pearl”) is consistently ominous. We’re talking about serial killers and their victims. It’s a jungle out there.

— Produced by Jimmy Kimmel, “High Hopes” begins streaming on Hulu. A reality series that puts the emphasis on workplace dynamics, it follows the routine at MMD, one of the oldest and best-established marijuana dispensaries in Los Angeles. Run by Slava and Mishka, immigrants from Belarus, it features the usual number of types, such as a no-nonsense manager and “bud-tender” and a former bouncer with a tendency to mess up but who has been all but adopted by the owner’s father, the “higher power” behind this stoner emporium.

Released to coincide with 4/20, the traditional day of weed-centric celebration, “Hopes” wisely dispenses with stoner humor. It opens with the first day of work of a new employee, a newcomer from Michigan who describes himself as an “all-day, every day” user of the product. His pipe dream is quickly dashed when he is curtly informed that getting high on the job is strictly forbidden.

The relatively new legality of the shop offers some peculiar complications, but for the most part “High Hopes” is a workplace comedy that tends to avoid the central question: Is marijuana use funny? A generation ago, the Rat Pack and other night club entertainers traded in jokes about booze, but it never occurred to anyone to set a show in a liquor store. “Cheers,” arguably the most popular series ever set in a bar, was paradoxically sober in its humor.

In some ways, “High Hopes” is as much about marijuana as “The Osbournes” was about heavy metal. The notion of a late-night talk show host producing a series about immigrant shop owners is hardly new. For years, David Letterman mined comedy from his awkward interactions with Mujibur and Sirajul, proprietors of the souvenir shop located just outside his studio. You don’t need to inhale to find “High Hopes” rather familiar.

— Slow-burn docuseries about true crimes and audacious criminals have become so commonplace it’s difficult to recall how riveting “The Jinx” was when it appeared on HBO in 2015. Now, after nearly a decade, “The Jinx: The Life and Deaths of Robert Durst” (10 p.m. Sunday, HBO, TV-14) returns.

As many fans of the original already know, the series had a profound impact on its subject, suspected murderer Robert Durst, who tried to flee the country as the original series concluded. “Jinx” 2.0 recalls his flight, arrest and subsequent conviction, and marinates viewers in an entourage of Durst confidantes who go to great lengths to display their loyalty to their very wealthy friend.
