Wenlei Ma The Nightly (AU) 4 days ago
A compelling thriller with a dry-as-London-gin sense of humour and an Oldman performance so abrasive that only he gets away with it. Go to Full Review

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

5/5
The sixth series of Slow Horses (Apple TV) has delivered, to borrow from Mick Jagger’s fabulously drawling title song, another strange game. But this year’s arc has been clean, taut and hugely satisfying too. Go to Full Review

Season Six of SLOW HORSES is more dangerous and more dour than Season Five, and it’s got me excited for Season Seven. Go to Full Review
James Delingpole The Spectator 1 day ago
Even by Slow Horses standards, this is ludicrously implausible. And also out-of-character -- which for a series that stands or falls on character (you’d never accept the convoluted plotting otherwise) is pretty close to inexcusable. Go to Full Review

Some actors exude the art from their pores. Oldman is one of them. Go to Full Review

Chris L @RT83891791 1 hr ago Worst season yet. Normally i would binge this the moment it was released. The characters had no development, in fact, it was if they were the losers their characters are boxed into. This was my favorite show. The characters had appeal. The new group is boring and just mouthy. If it wasn’t for River, Jackson and Diana it would be unwatchable. See more Zachary S @Zach154 20 hrs ago Slow Horses continues to deliver in Season 6 with its sharp, snappy writing and consistently compelling stories and characters. Gary Oldman remains a standout, while Hugo Weaving brings a menacing presence that adds another layer of tension. The rest of the cast gets plenty of moments to shine, with everyone feeling fully integrated into the story. The stakes remain high throughout, and the show does an excellent job making the danger feel genuine, leaving you constantly wondering who might not make it out. Another tense, entertaining, and brilliantly acted season. See more Drew M @Stonehands211 23 hrs ago Top tier season! This show loves to build up new and great characters and kill them off super coldly! See more Yue L @RT42810620 1 day ago Terrible. Season 6 just gets worse and worse. The Slow Horses may be comically incompetent, but this is just infuriating. Standish seems to be the only person that understands they are MI5, whilst the rest are all children. Yes, that is the joke, but it's been years now and surely they've had some character growth? They argue, stand in windows and miss every bullet, including Flyte, who is supposed to be the competent one- yet in her final scene she runs up to a person with their back turned but still shoots from afar (and misses), and also doesn't count her ammo remaining (while wasting ammo constantly). The Russian spies are so annoying, their scenes are stupid and make no sense. Coe has the jump on the guy but decides to give him the heads up. The girl manages to surprise Sid in the forest, even though the leaves would be rustling and give her position from miles away. Harkness trying to kill the "kid" doesn't really make sense. Why would Taverner even make a secret hit in Russia?? See more Paul H @RT94476332 1 day ago Season 6 was a major letdown. The Slow Horses were neutered this season. They barely did any spying, solved almost no mysteries, and never acted tough. Most of the time they went in unarmed and not paying attention. The only lesson I took away is that the bad guys always win, because the Slow Horses got very few wins. If this is the path the show is taking, I hope they end it. Whoever wrote this season did the show no favors. See more Lorena G @LorenaGL 1 day ago It still having the magic and what makes this show an outstanding (it should be a world phenomenon) but in this Season I felt more than ever than we need more episodes, sometimes you feel the rush. Great performances, direction and twists. See more Read all reviews
