Apple TV+ has built a reputation for top-tier sci-fi and feel-good comedies, but its spy thriller Slow Horses has quietly become the platform's most reliable juggernaut. With six seasons in just four years, the show has earned near-universal praise and a growing audience. Now, as its sixth season finale approaches, the series is closing in on a remarkable streaming milestone that underscores its staying power.
Based on Mick Herron's novels about disgraced MI5 agents relegated to a dumpy office called Slough House, Slow Horses premiered in 2022 to strong reviews for its sharp writing, tense pacing, and standout performances. The show's production strategy was unconventional from the start: Apple TV+ ordered two seasons at a time, each with six episodes, allowing for a rapid release schedule. That pace took a toll on creator Will Smith, who exited after Season 5, citing the difficulty of maintaining quality under such a demanding workload. Fans worried, but those fears were quickly put to rest when Season 6 debuted to the best reviews yet, earning a perfect 100% "Certified Fresh" score on Rotten Tomatoes.
The series stars Gary Oldman as Jackson Lamb, the slovenly but brilliant head of Slough House, alongside Jack Lowden, Olivia Cooke, and Kristin Scott Thomas. Its overall Rotten Tomatoes score sits at an impressive 98%, placing it among the most acclaimed shows of its era. Collider's Carly Lane praised Season 6 as "the biggest turning point for Apple TV's longest-running spy thriller," noting how it masterfully bridges past and present while setting up an intriguing next chapter.
According to FlixPatrol, Slow Horses is on track to hit 700 days on the domestic Apple TV+ viewership chart, a feat that speaks to its enduring popularity. With Season 7 already confirmed, the show shows no signs of slowing down. The Season 6 finale airs on October 21, and fans are eagerly awaiting what comes next.
For those new to the series, it's worth checking out the truth behind Slough House to understand the show's unique appeal. And if you're in the mood for more spy thrills, this gripping Apple TV+ thriller is a great binge option. Slow Horses continues to prove that Apple TV+ has a winner in its corner, and with Season 7 on the horizon, the streak is far from over.
