Is Reacher Season 4 Worth Watching? Our Honest Review
The short answer is yes. The longer answer is that this might be the most ambitious season yet.
Reacher has always been a show that knows exactly what it is. Big guy walks into town, bad people underestimate him, bones get broken. Seasons one through three perfected that formula in small-town settings where Reacher was the smartest and most dangerous person for miles. Season four changes the equation. He's in Philadelphia now, surrounded by people who are just as ruthless, and for the first time in the show's run, you get the sense that he might actually be in over his head. It's a bold evolution for a series that was already one of Prime Video's biggest global hits.
The setup is deceptively simple. Reacher spots a woman on a late-night subway who's displaying all the signs of a suicide bomber. Before he can intervene, she's dead. But the explanation doesn't add up, and what follows pulls him into a conspiracy involving a congressman with a classified military past, a missing thumb drive, and a chief of staff who takes a swan dive off a building rather than answer questions.
What makes this season stand out?
The show has always adapted Lee Child's novels, and season four takes on Gone Tomorrow, published in 2009. The adaptation updates the geopolitics for 2026, which gives the conspiracy a sharper, more contemporary edge. The tone has shifted too. Collider called it "the show's bleakest, most furious, and most demanding season so far, a mystery thriller that will have audiences on edge." Rotten Tomatoes' editorial team described it as "darker and more complex, but packed with brutal action." It holds a 93% on Rotten Tomatoes from 29 reviews and a 91% audience score, matching the series high from season one.
The Rotten Tomatoes critics' consensus reads: "Reacher maintains its formula for maximum entertainment, serving more brawn, enough narrative brains, and always the right amount of Alan Ritchson to keep the operation up and running for seasons to come." Metacritic assigned a score of 77, indicating "generally favourable reviews." Forbes noted that the 91% audience score matches the best of all four seasons.
The fights hit harder
The choreography this season is the most brutal the show has ever produced. Rotten Tomatoes' editorial team wrote that "the fights are more brutal, the hits feel harder, and our titular hero is really tested." There's a cage fight in episode two that's already being talked about as one of the best action sequences in any streaming show this year. The show has always delivered on its action promises, but season four takes it to another level entirely.
Alan Ritchson is joined by Sydelle Noel as Detective Tamara Green, an NYPD homicide cop who starts working with Reacher after realising he's onto something real. Agnez Mo and Anggun also join the cast, along with Marc Blucas as Congressman Sampson, the man at the centre of the conspiracy. Kevin Corrigan and Kathleen Robertson round out the new additions. It's the strongest ensemble the show has assembled.
The verdict
Four seasons in, Reacher has done what very few action shows manage: it's evolved without losing what made it work in the first place. The show has traded small-town charm for big-city intensity, and the result is its most gripping season yet. It reclaimed the number one spot on Prime Video within two days of premiering, knocking Sterling Point off the top, and season five has already been confirmed before this one has even finished airing. That confidence from the studio tells you everything. Reacher season 4 is streaming now on Prime Video.
New episodes drop every Wednesday through 16th September.
