Slow Horses is our returning-series choice on Apple TV+ this week. Apple dates season six to September 16, giving existing viewers a reason to return to Jackson Lamb’s team. For newcomers, the more useful recommendation is to try the beginning: its failed-spy workplace gives the espionage a distinctive source of tension before any complicated assignment gets underway.

Why this return is worth considering
Gary Oldman’s Jackson Lamb leads British intelligence agents whose career mistakes have landed them in MI5’s unwanted department. That premise gives the series two sources of pressure: threats outside the office and colleagues who can make one another’s jobs harder. Choose it if you enjoy espionage with abrasive personalities and dark humor. The team’s professional embarrassment is part of the appeal, especially for viewers who find immaculate, all-capable screen spies less interesting.
New here? Give the first episode a fair try
Apple’s U.S. page lists the first season’s six episodes, beginning with River Cartwright’s arrival at Slough House in Failure’s Contagious. The pilot is listed at 54 minutes. That makes one episode a practical trial before committing to the larger series. Watch for whether the office dynamic holds your attention alongside the spy story; if it does, the first season offers a manageable starting run.
Returning viewers can check the new season
The September 16 date on Apple’s press page is a premiere date. It should not be read as a promise that every sixth-season episode is available together. Returning viewers should open the season selector to see the currently playable installments. The U.S. title page rates the show TV-MA and flags language and violence, making this an adult viewing choice rather than a family adventure. For this week’s queue, choose the latest season if you are caught up, or the pilot if Lamb’s department is new to you.
