Apple TV+’s espionage drama Slow Horses is gearing up for its sixth season, and early critical responses suggest the latest batch of episodes may be the series’ strongest yet. Set to debut on September 16, the season kicks off with a single installment before rolling out weekly through October 21.
New Direction, Same Edge
Season 6 introduces fresh leadership behind the scenes. With a new showrunner and lead writer at the helm, the series also departs from its usual adaptation approach by drawing from two of Mick Herron’s novels rather than one. Yet despite these shifts in creative direction, reviewers seem united in asserting that the show’s quality hasn’t suffered—in fact, many say it’s improved. What’s clear from early reviews is that the transition has yielded a sharper, more intense thriller experience.
Reviews Rave: Best One Yet
Sites like Awards Buzz have already dubbed season 6 “the best one yet,” while Decider praises Slow Horses for being a “remarkable, larger-than-life feat for the small screen”—a high bar that the series appears to meet. Comic Book Club notes that almost every episode features unexpected twists, cliffhangers, or significant character developments. Reviewers at Next Best Picture report that despite the behind-the-scenes shakeups, the show remains relentless in delivering what made it essential viewing last season.
Slow Horses is one of Apple’s most critically acclaimed original series. Among its uncommon achievements is releasing a new season every year without fail—and signs are pointing to that rhythm carrying on. Work is already underway for future seasons, keeping fans on their toes.
This upcoming season, then, will be vigilantly watched—not just for its plot and performances, but for how it balances change and continuity under its new creative team.
What this means: Slow Horses Season 6 could redefine what fans expect from the show. With its blend of fresh energy and established tone, it may also shift how Apple TV+ handles adaptations, creative transitions, and annual release cycles. If the early buzz holds, this season could be the benchmark for everything that follows—not just for Slow Horses, but for serialized espionage dramas across streaming platforms.
