How Much Watching Time Do You Have This Weekend?

‘Barry’
When to watch: Sunday at 10 p.m., on HBO.

“I know they say you did a bad thing, but I’m sure you’re not a bad guy,” a prison guard tells Barry (Bill Hader) in the Season 4 premiere. Oh, brother, you don’t know the half of it. This final season — sob — is as relentless and brilliant as ever, the show’s blend of hilarity, depravity, profundity and tricksterism in astonishing balance. Barry is a bad guy, of course, a very bad one, a (mostly) remorseless assassin, torturer and abuser. But he’s not opaque obsidian; he’s a prism, and “Barry” lets us see a full range of refraction. Two episodes air on Sunday, and the next six air one at a time.

… an hour, and I like a good bus.

‘Rennervations’
When to watch: Now, on Disney+.

The actor Jeremy Renner and a cadre of fabricators revamp large vehicles for various charities in this warm reality series (which was filmed before Renner’s recent snowplow accident). One way to look at “Rennervations” is as an example of present-day philanthropy “content” that depicts altruism but ultimately serves to make money for a large corporation. Another way to look at it is as a throwback to shows like “Pimp My Ride” and the early, purer seasons of “American Chopper,” with a sunny, Disneyfied aura. You like helping kids? Well, we put a recording studio, performance space and music lounge on a bus so you can, uh … drive around and help kids make music. OK!

‘The Good Mothers’
When to watch: Now, on Hulu.

This Italian drama (in Italian and Calabrian, with subtitles) is based on a true story and follows the saga of the women who brought down the ’Ndrangheta mafia. When Denise (Gaia Girace) and her mother travel to Milan to reunite with her father, she is excited at first. But dread starts creeping in, and then her mother disappears — all while an ambitious, resolute prosecutor is putting together an elaborate Crazy Wall. If you liked “Gomorrah” or “The Last Panthers” but want something less bleak and grimy, watch this. There are six episodes.
