_The Diplomat_ is an absolute triumph of storytelling. Debora Cahn's brilliant political thriller incorporates the best elements of her most high-profile TV work to date, mixing the relentless pacing of _Homeland_, the complex relationship portrayals of _Grey's Anatomy_, and the resolutely smart dialogue & sky-high audience expectations of the Sorkin years of _The West Wing_. Throw that into a brew along with a flawless cast and you get a show that is nigh impossible to stop watching mid-binge. Keri Russell's return to TV after her iconic run on _The Americans_ does not disappoint, as she portrays yet another strong, brilliant woman in a position of power whose femininity is as often an asset as is can be a hinderance- but is simply and effortlessly incorporated into the character as fact. Even as she grapples with imposter syndrome she never loses sight of her strengths. She knows that she can stand toe-to-toe with her legendary-in-diplomatic-circles husband. (In fact, she warns her new colleagues that she's the only one who can help them decode or resist his charms.) Watching their sometimes partnership / sometimes rivalry unfold across the 8 episodes is mesmerizing as both she & Rufus Sewell mercilessly chew up every scene, their competition-mixed-with-collaboration showing up not just in the words that they speak, but in a showcase of two preternatural acting talents who are used to stealing scenes from other actors trying to outdo each other. And Sewell more than holds his own. He shines as the other Ambassador in their marriage who's grappling with a crumbling relationship that he wants to save, but doesn't seem to know whether it's because he loves his wife or if she offers him a new pathway to power. The overarching mystery of the series blends seamlessly with the evolution of their relationship, with neither feeling forced or unrealistic. And the area where so many shows can falter - the supporting roles - is yet another where this one rises above expectations. All of the secondary players shine, with the only ding against the series being the underutilization of Jess Chanliau's Ronnie. But, the again, the hallmark of the series seems to be making sure that you always want to see more. Here's hoping that we get to see more of Ronnie in (a hoped-for) season 2.
