It’s amazing how shows fueled only by fast talk can feel as gripping as any thriller out there. The Diplomat is cerebral and heavy on geopolitical jargon, but somehow, it manages to feel genuinely exciting, each new episode impossible to not play next. Thanks is due in large part to Keri Russell who, fresh out of her incredible stint in The Americans, returns here as messy and intense and endearing as ever. On the one hand, The Diplomat is about the delicacy of diplomacy, about how every decision made at this level has ripples of consequences throughout the globe. But it’s also, amusingly, a marriage story. Russell plays a woman who has long been defined by her more renowned if egotistical husband, played perfectly by Rufus Sewell. They have a complex relationship that is as much a career partnership as it is a romantic one, and part of the show’s charm is blending all these story arcs seamlessly. Fans of West Wing, Veep, and Homeland will find much to like in this series, especially because of its informative takes and engaging performances.
