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.

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.

3/5

Slow Horses is still slick and confident enough, and it helps itself by casting Lenny Rush, an actor who immediately improves anything he’s in, as a civilian caught in this year’s crossfire. But it might have run its course.

After a Season 5 stumble—still good but definitely the series’ weakest offering—Slow Horses Season 6 returns to tiptop form.

9/10

Whether this ends up being Oldman’s final role or the launching pad for Jack Lowden to become 007, Slow Horses‘ sixth season is its best yet and one of the best seasons of television of the year.

Gary Oldman's Jackson Lamb is one of the great characters that streaming has produced, ever. Supporting cast is terrific - cynical, smart and broken in some relevant way. Storylines are tight, entertaining and pithy. Highly recommended.

In the sixth season here, and it's steady as she goes. Still luring us into a world of unbending anti-heroes navigating a bendable, brave new world.
