5/5
... Despite the whole thing being an "anti-spy" thriller, this isn't Le Carré — it's a whole lot funnier. Go to Full Review Mike Hale New York Times Sep 16, 2024
Slow Horses” remains one of the most entertaining and well-put-together shows around. The motions through which it goes are good ones. Go to Full Review Camilla Long The Times (UK) Sep 11, 2024
It’s still utterly brilliant. Go to Full Review Jacob Robinson The Saturday Paper Jul 16, 2026
Looming over this season is the fascinating question: what happens when an ageing spy starts to lose their sense of reality and how quickly do they become a national security risk? Go to Full Review Marta Medina Pérez mundoCine Aug 15, 2025
4/5
It retains the dark humour that has defined the series from the start, as well as the espionage-thriller thread, nailing that ‘strange game’ between spies referenced in Mick Jagger’s memorable and catchy main theme.

And yet, in all its downtrodden glory, Slow Horses remains a thing of beauty. It’s hard to look away from a series that feels so lived-in, so utterly convinced of its own grimy brilliance. Go to Full Review Read all reviews

Drew M @Stonehands211 Aug 14, 2026 The finale of this season was the best of the series yet. Absolutely intense and devastating. Its everything that’s great about this show. See more Ken H @RT20423466 Aug 5, 2026 Feels a lot dumber this season. The plot moves forward whichever character is on screen doing a dumb cliche thing like a cheap horror movie. See more Thomas S @RT39405909 Mar 15, 2026 This is the best so far - good intrigue , action and twists. Well done. That the RT ui is so horrible on mobile devices and the rt app is worse - on the other hand,rt gets 0 stars. See more Kurt K. @Kurtosaurus Jan 29, 2026 One of the best seasons! See more m G. @mgoff62 Jan 15, 2026 love this and jackson lamb!! See more Julian P @JulianPoulter Dec 12, 2025 Not as good as the previous 3 series and it really feels like Jack Lowden's character needs to start becoming stronger but he didnt. Still very good but a few characters are starting to caricature. See more Read all reviews
