Season 4 Ratings & Reviews
New York Times
Mike Hale
Slow Horses" remains one of the most entertaining and well-put-together shows around. The motions through which it goes are good ones.
The Atlantic
Sophie Gilbert
Slow Horses is thrilling, often improbably so. But it's also keenly attuned to the dynamics and psychology of the trade -- what it means to understand people as expendable pieces in an unwinnable game.
San Jose Mercury News
Randy Myers
"Slow Horses'" complex characters continue to hash out their issues this season, and while everyone is exceptional, this is Lowden's finest hour.
Entertainment Voice
Alci Rengifo
"Slow Horses" never rushes and also never feels like a grueling slow burner. Like any good thriller, it doesn't waste time and pays meticulous attention to how the plot should weave together by the end of the season.
Decider
Joel Keller
Slow Horses continues to be entertaining because of the show's quirky characters, not the least of which is Oldman's character Jackson Lamb.
Epoch Times
Michael Clark
[Director] Randall's biggest achievement here is in not messing about with what came before. As with the directors of the previous seasons, Randall strictly adheres to Smith's vision of what the latter has described as the "anti-Bond."
Chicago Tribune
Nina Metz
Tackling a new case each season, while keeping the same format and framework, is enormously satisfying when done well.
Rolling Stone
Alan Sepinwall
No homework is required, nor is it difficult to get up to speed on what's happening. You can just dive right into the latest adventure on this enormously entertaining show -- and if you haven't yet, you should.
Pop Culture Maniacs
Jean Henegan
Smart, funny, and emotionally resonate (there's some sad, dark moments this time around that will undoubtedly reverberate into season five), this latest Slow Horses season is well worth your time.
Geek Girl Authority
Diana Keng
Slow Horses Season 4 continues the series's trademark thrilling, complex, and devastating narrative bent while innovating new developments to keep us on our toes.
Beverly Hills Courier
Neely Swanson
There is no greater pleasure than to watch Gary Oldman work his magic on screen with the incomparable Kristin Scott Thomas, the wryly deadpan Joanna Scanlan and the brilliant Jonathan Pryce.
Collider
Jeff Ewing
In Season 4, the hidden histories of the Cartwright family are revealed, creating an engaging and tension-ridden hunt for the truth.
The Establishing Shot
Jeff York
As impossible as it may sound, the new set of six episodes is the best yet.
AV Club
John DeVore
It subverts the traditional spy story and reinvents it as a drama about a dysfunctional family. There is vinegary comedy and bone-cracking violence, too.
The Spool
Tim Stevens
[Adam] Randall's work here is the most satisfying deployment of his skills to date.
CBR
Howard Waldstein
Season 4 of the best spy series on TV uncovers hidden agendas and poignant truths.
Awards Buzz
Abe Friedtanzer
For fans of the show, season four won't be a disappointment, pivoting to a new storyline that incorporates all the entertaining elements audiences have come to expect.
Paste Magazine
Kaitlin Thomas
One of the joys of Slow Horses is its ability to balance an inherently dramatic narrative with a wry sense of humor. That still exists, but Season 4 is more personal, and, thus, feels more consequential than its predecessors.
FandomWire
Sean Boelman
Season 4 of Slow Horses is firmly the best of the show yet, boasting the most exciting and complex story we've seen so far
Loud and Clear Reviews
Claire Fulton
Such impressive performances really highlight how much this series values its characters. [...] The genuinely compelling - and surprisingly poignant - narrative is just a bonus, because it's in the spies that this spy caper has always found it's magic.
