Why Slow Horses Season 6 Set an Unwanted Rotten Tomatoes Record

Slow Horses season 6 has hit a milestone that the Slough House team would rather forget: it now holds the lowest Rotten Tomatoes score in the show's history. The Apple TV+ spy drama, starring Gary Oldman as the irascible Jackson Lamb, has earned critical acclaim since its 2022 debut, with each previous season scoring above 90% on the review aggregator. Season 6, however, has dipped below that benchmark, sparking debate among fans and critics alike. While the series remains a standout in the crowded espionage genre, the dip suggests that even the most beloved shows can face creative headwinds. The new season continues to adapt Mick Herron's Slough House novels, but some reviewers argue the plot feels more convoluted and less character-driven than earlier outings. Others point to the challenge of maintaining tension after five seasons of high-stakes spy games. Despite the record, Slow Horses remains one of Apple TV+'s most-watched originals, and the ensemble cast—including Kristin Scott Thomas and Jack Lowden—continues to draw praise. The question now is whether season 7 can restore the show's near-perfect track record. For a series built on underdogs defying expectations, a comeback would be fitting.
