Best Medicine Renewed for Season 2 at Fox as Eliza Coupe Joins Season 1 Finale
Fox is sticking with its newest feel-good hit.
The network has officially renewed Best Medicine for a second season set to air during the 2026–27 television season. While the announcement excites fans, it doesn’t come as a shock. The dramedy has quietly become one of Fox’s strongest performers this year, delivering solid ratings and building steady audience momentum.
And that’s not the only big news. Eliza Coupe is stepping into the story just in time to stir things up in the final two episodes of season one.
Why Best Medicine Became a Breakout Hit
From its premiere, Best Medicine struck a chord with viewers. The series blends sharp humor with emotional storytelling, giving audiences both laugh-out-loud moments and heartfelt drama.
The show currently averages 6 million viewers across platforms within seven days of each episode’s release. Even more impressive, the Jan. 4 premiere has accumulated 12.6 million viewers to date — a major win in today’s fragmented TV landscape.
Fox Television Network president Michael Thorn praised the show’s success, calling it a breakout series that balances humor and heart. He credited showrunner Liz Tuccillo’s creative vision and Josh Charles’ performance for connecting with audiences.
That connection is exactly why the network is confident heading into season two.
A Fresh Take on a Beloved Format
Best Medicine is the American adaptation of the long-running British series Doc Martin.
The story follows Dr. Martin Best, played by Josh Charles, a once-celebrated Boston surgeon who abruptly leaves his high-powered career behind. He returns to Port Wenn, a small fishing village where he spent childhood summers, and starts over as a general practitioner.
The setting provides much of the show’s charm. Instead of the fast-paced chaos of a big-city hospital, viewers are immersed in the slower rhythms of small-town life — where everyone knows each other, privacy is limited and personalities often clash.
The supporting cast helps bring that world to life, including Abigail Spencer, Josh Segarra, Annie Potts and Cree. Together, they create a mix of warmth, conflict and community that feels both comforting and unpredictable.
Eliza Coupe Enters the Picture
Just as the show gears up for its season finale, a new character is about to complicate Dr. Best’s life.
Eliza Coupe will guest star in the final two episodes of season one as Dr. Eden Montgomery — Martin’s former girlfriend from medical school.
Eden isn’t just any ex. She’s described as essentially the female version of Martin: socially awkward, blunt, highly intelligent and completely self-assured. Now a successful fertility specialist, she arrives in Port Wenn to help a patient.
But she also has another mission — to win Martin back.
Her arrival promises emotional tension, unresolved history and possibly a shake-up in Martin’s current relationships. Given Coupe’s track record in comedy and character-driven roles, her presence is likely to inject both sharp humor and dramatic sparks into the finale.
What Season 2 Could Explore
With the renewal locked in, the big question becomes: where does the story go next?
Season one has focused largely on Martin’s adjustment to small-town life and the emotional baggage he brought with him from Boston. His struggle to connect with patients and neighbors — despite genuinely wanting to help — has been central to the show’s appeal.
Season two could expand in several directions:
1. Relationship Fallout
If Eden’s attempt to rekindle her romance with Martin succeeds — or even partially succeeds — it could shift the emotional landscape of the series. Alternatively, her presence could force Martin to confront parts of his past he’s been avoiding.
2. Deeper Community Ties
As Martin becomes more integrated into Port Wenn, the series may lean further into community-driven storylines. Small-town dramas, personal conflicts and evolving friendships can all fuel long-term character growth.
3. Professional Challenges
Although Martin stepped away from elite surgery, his medical expertise still sets him apart. Season two may explore more complex medical cases that test his decision to leave his former career behind.
Why Viewers Are Connecting
Part of Best Medicine’s success lies in its balance. It never feels overly heavy, but it doesn’t shy away from emotional depth either.
Martin is not an easy character. He’s socially rigid, often blunt and sometimes frustrating. But that vulnerability beneath his tough exterior makes him compelling.
Audiences are responding to that layered portrayal. In an era where many shows aim for spectacle, Best Medicine thrives on character-driven storytelling and grounded emotional stakes.
The combination of heartfelt moments and dry humor makes it accessible to a wide audience — from viewers who enjoy medical dramas to those who prefer relationship-focused storytelling.
Fox’s Growing Confidence in Character-Driven Series
The renewal of Best Medicine signals something important for Fox.
While flashy high-concept dramas and reality competitions still dominate network schedules, there’s clearly room for smart, emotionally grounded dramedies.
By investing early in a second season, Fox is showing confidence not just in the ratings, but in the long-term storytelling potential of the series.
The show is produced by Fox Entertainment Studios, with Liz Tuccillo serving as executive producer alongside Ben Silverman, Rodney Ferrell and Howard T. Owens of Propagate Content, the company that brought the Doc Martin format to the U.S. Mark Crowdy and Philippa Braithwaite, executive producers of the original British series, are also involved.
That collaborative production team blends American network sensibilities with the DNA of a globally proven format.
The Road Ahead
For now, all eyes are on the final two episodes of season one.
Eliza Coupe’s arrival as Eden Montgomery adds a fresh emotional wrinkle just as the story reaches a pivotal moment. Whether she disrupts Martin’s new life or pushes him toward personal growth, her impact will likely carry into season two.
With strong ratings, a loyal audience and a renewal already secured, Best Medicine is no longer just a promising freshman series. It’s shaping up to be a cornerstone of Fox’s upcoming lineup.
The only prescription viewers need now is patience while they wait to see how season one ends — and how much messier Dr. Martin Best’s life is about to become.
