Here's the thing about Best Medicine: it knows exactly what it is, and it refuses to apologize. The series wears its DNA on its sleeve - curmudgeonly doctor, picturesque town, will-they-won't-they tension with a local woman he's constantly insulting - and then goes about the work of making that familiar blueprint feel lived-in and, occasionally, genuinely surprising.
The engine is Josh Charles. He plays Martin Best as a man who considers basic human pleasantness a form of medical malpractice. His deadpan is devastating; he can deliver a line about blood pressure like it's a personal insult and make you laugh out loud. But the trick Charles pulls off is subtler than the jokes. Underneath all that smugness, he lets you see the flicker of a guy who genuinely doesn't understand why people keep wanting things from him. It's a performance built on micro-reactions, and this season gives him more of them - moments where the mask slips just enough to be human without ever going soft.
The supporting cast keeps the whole thing from becoming a one-man misanthropy showcase. Abigail Spencer brings warmth and steel in equal measure as Louisa, giving as good as she gets instead of just melting under Martin's barbs. Josh Segarra's Sheriff Mylow is a reliable comic punchline machine but gets a few quieter beats too. Cree's Elaine is the show's secret weapon - the everyday competence that quietly runs circles around Martin's ego. And Annie Potts as Aunt Joan is pure laid-back chaos, the kind of relative who says something devastating and then offers you a cookie.
Where Season 2 stumbles is where most shows of this genre stumble: the episodic patient-of-the-week plots can feel weightless. A few subplots wobble toward predictable conclusions, and the show occasionally confuses "quirky" with "written." At 42 minutes an episode, the pacing can drag when the week's medical mystery isn't as interesting as the people standing around it.
But when Best Medicine works - and this season, it mostly does - it's the sort of show you sink into. It's funny, it's warm without being saccharine, and it understands that the best comedy comes from people who genuinely annoy each other but can't quite walk away. The tonal balance between comedy and drama is handled with real finesse, never whiplashing the audience from a laugh to a genuine emotional gut-punch without earning it.
