Review of 'Slow Horses' Season 6: A Dark Turn for Apple TV's Spy Thriller

The sixth season of 'Slow Horses' is set to premiere on September 16 on Apple TV, continuing the acclaimed spy drama that has captivated audiences since its debut in 2022. This season adapts two novels from Mick Herron's series, 'Joe Country' and 'Slough House', and follows the misfit MI5 agents led by Jackson Lamb, portrayed by Sir Gary Oldman. As they navigate a dangerous situation involving mysterious assassins, the narrative takes a darker turn, exploring themes of grief and violence while still delivering the show's trademark humor.

Diana Taverner, played by Kristin Scott Thomas, finds herself in a precarious position of power, facing off against manipulative figures like Peter Judd and Damien Cantor. The season also sees River, portrayed by Jack Lowden, grappling with personal challenges while developing a romantic subplot that adds depth to his character. The introduction of new characters, such as Reece Nesmith, played by Lenny Rush, brings fresh dynamics to the story.
