Worth Watching — October 3, 2026

HBO’s superhero saga Lanterns ends with revelations about the murder of Hal Jordan (Kyle Chandler). The penultimate episode of the Masterpiece mystery Marble Hall Murders takes a step closer to solving a real and fictional murder. The Yellowstone spinoff Marshals opens its second season with the Montana crew rallying to rescue Kayce Dutton’s kidnapped son. Sharon Horgan‘s cringe comedy Youth offers its conflicted heroine a new/old suitor.

Lanterns

Who killed former Lantern Hal Jordan (Kyle Chandler)? That mystery haunts the season finale of the engrossing and emotionally charged superhero drama, as the disaffected John Stewart (Aaron Pierre) joins forces with the “Halogram” version of Hal’s consciousness (Chandler making the most of this dual role) in one of TV’s more unusual and entertaining buddy capers. The solution will force John to face his fears—“Don’t be afraid to be afraid,” Hal tells John in the teaser—and make pivotal moral decisions in a series that pierces the armor and gets to the heart of what it means to be a hero.

Marble Hall Murders

As this meta-Masterpiece mystery nears its conclusion, the fictional detective Atticus Pünd (Tim McMullan) takes a back seat to real-life Detective Inspector Ian Blakeney (Danny Sapani). He’s investigating the hit-and-run murder of troubled author Eliot Crace, whose editor, Susan Ryeland (Lesley Manville), is the prime suspect. When he begins to see Susan as a victim after her flat is ransacked, she tries to convince him that the solution to Eliot’s murder, and the death 20 years ago of Eliot’s fearsome grandmother, lies in the pages of the novel Eliot was writing. All will be revealed in next week’s finale.

Marshals

It’s never easy being a Dutton. As the second season of the Yellowstone spinoff opens, former Navy SEAL-turned-rancher-turned-U.S. Marshal Kayce (Luke Grimes) once again grapples with his family’s violent legacy when his son Tate (Brecken Merrill) is kidnapped and becomes a pawn in the crooked Tom Weaver’s (Chris Mulkey) attempt to grab Kayce’s East Camp land at any cost. “Won’t be the first time I traded vengeance for my family’s safety,” Kayce concedes as he prepares to make a deal—but anyone who knows the Duttons knows they never give up without a fight. And once his fellow marshals catch on that Kayce and Tate are in peril, it’s all hands on deck.

Youth

Sharon Horgan (Catastrophe, Bad Sisters) has created another memorably messy heroine in her latest comedy of cringe as Alex, a single-mom divorcee entering her sixth decade with neurotic trepidation. Desperate for companionship, she reluctantly lets her ardent admirer, Michael (Tim McInnerny), who’s roughly a decade older, back into her life. “Lean on me,” he tells her, though it’s obvious the attraction isn’t mutual. What could possibly go wrong?

The Simpsons

The Studio‘s Ike Barinholtz is this week’s guest voice when Bart and Lisa go ape over an abandoned baby chimp they adopt, then have to rescue when the animal is snatched by a private zoo. Good luck counting on Homer, who’s not exactly the most evolved primate himself. Followed by new episodes of Animal Control (8:30/7:30), Universal Basic Guys (9/8c), and Grimsburg (9:30/8:30c).
