Kevin Costner has been a beloved Western staple for decades, but it wasn’t until 2018’s Yellowstonefrom franchise mastermind Taylor Sheridan that he became a staple of neo-Westerns, too. And one of his best is set to land on streaming in the new year.

Directed, written, and co-produced by Thomas Bezucha, and based on the 2013 novel of the same name by Larry Watson, 2020’s Let Him Go casts Kevin Costner alongside Academy Award-nominee Diane Lane as a couple who find themselves walking headfirst into danger after their beloved grandson is taken from them. Starring Lesley Manville, Kayli Carter, Will Brittain, and Jeffrey Donovan alongside Costner and Lane, Let Him Go is a slow-burning thriller that will leave you heartbroken as well as offering the violence you inexplicably crave. Let Him Go is all set to land on Peacock on January 1, 2026, and you can check out the official synopsis below…

Following the loss of their son, a retired sheriff and his wife leave their Montana ranch to rescue their young grandson from the clutches of a dangerous family living off the grid in the Dakotas.

‘Let Him Go’ Is a Slow-Burning Revenge Thriller With a “Brutal Climax”

Let Him Go proved to be a powerful hit with critics and audiences alike at the time. The neo-Western thriller holds scores of 85% from critics and 76% from audiences on Rotten Tomatoes, with the consensus heaping praise on the cast while criticizing a somewhat uneven blend of adult drama and revenge thriller. While MovieWeb’s own Julian Roman struggled a little with the slow-burning nature of Let Him Go, he heaped praise on the “brutal climax” and “simmering tension.”

Rival grandmothers fight for the custody of their grandson in a slow-burn, neo-western thriller. Let Him Go builds simmering tension until an explosion of graphic violence. The film takes the time to establish serious character depth before throwing its leads off the deep end. The pacing gets a bit sluggish, but revs up for the brutal climax. The period setting’s desolate landscapes add to the foreboding narrative.

Similarly, Collider advised that audiences not go into Let Him Go expecting a loud action movie, describing the movie instead as a “sensitive vigilante tale.” Chicago Sun-Times, meanwhile, called watching Kevin Costner and Diane Lane share the screen “movie heaven,” with RogerEbert.com concluding, “Understated in its quiet rhythms and vast beauty, [Let Him Go] is fortified with strong performances and, eventually, punctuated by shocking moments of violence.”

Following Kevin Costner’s unceremonious departure from Yellowstone, Taylor Sheridan’s neo-Western series continues to forge ahead with all manner of spin-offs on the horizon. And speaking of horizons, Costner continues to fight to bring old-fashioned Western epics to the screen…though he’s had some trouble along the way. His hugely expensive Horizon franchise may have ended three movies earlier than the actor and director planned, with Horizon: An American Saga – Chapter 2 having been delayed indefinitely, with Costner himself now facing multiple lawsuits regarding misconduct on set.
