4/5
I urge you, do not lose a minute. This is by far and away the best season of the lot, no notes. Go to Full Review
Ben Dowell The Times (UK) Sep 16, 2026
5/5
Based on Joe Country and Slough House, the sixth and seventh in Mick Herron’s book series, it is a clever adaptation that produces a crisp, clean story, weaving heart-stopping action. Go to Full Review
Nick Hilton Independent (UK) Sep 16, 2026
3/5
The show is beautifully shot, the action sequences well choreographed, and the tension executed with aplomb. It might not be much interested in reinvention or evolution, but this is prestige entertainment at its absolute sturdiest. Go to Full Review

Some actors exude the art from their pores. Oldman is one of them. Go to Full Review
Tim Stevens The Spool Sep 29, 2026
After a Season 5 stumble—still good but definitely the series’ weakest offering—Slow Horses Season 6 returns to tiptop form. Go to Full Review

Paul H @RT25780649 18 hrs ago Took way too long to get to the action and the agents did not do what they do best. River never armed himself against the assassins. They shined in the previous seasons. Very Lackluster at best. It just keeps building with little resolution. See more P F @petef 20 hrs ago The is the best looking & best directed season. Still the same characters but with a fresh perspective. See more Noelle T @RT83882966 21 hrs ago Terribly written season. It’s gutting as this was my favourite show. This season has a different head writer and it really shows. Please dear god bring back Will Smith as a writer. See more Siberian M @RT81291965 21 hrs ago It's getting better towards the end of the series. All episodes are better for binge-watching. I am still waiting to see how the ending is going to diverge from one in the books. See more J D @JayDog123 21 hrs ago After a somewhat disappointing series 5 - glad to see the show back to being great. See more Nick K @nickjkirby 23 hrs ago Four episodes in and it's the first time I've ever considered not going through to the end of a season of Slow Horses. It's all just a bit slow and ponderous - the blackmail of Diana is drawn out, the assassins are just a trope - but worst of all is Hugo Weaving rehashing Mr Smith from The Matrix (almost unwatchable). And then they get rid of one of the best characters. The new showrunner is clearly trying to make their mark - but I'm not convinced they've succeeded. See more Read all reviews
