David Bianculli NPR Oct 31
When the writing and the direction are this excellent and the actors every bit as good, scenes just soar. The silences are as powerful as the dialogue, and every conversation is bound to shift the interpersonal dynamics, often profoundly. Go to Full Review James Jackson The Times (UK) Oct 17
4/5
It’s the sort of series where, at the end, you look back and realise quite how close to demented the affairs of state — and the loins — have been and how much you don’t mind. Not when it’s this savvy and entertaining. Go to Full Review Sam Adams Slate Oct 17
It’s smart, except when it’s dumb. Go to Full Review Yamily Habib LatinaMedia.Co Nov 11
Here is the bitter core that Season 3 refuses to spit out: Competence, when performed by a woman, becomes a service. It is not a path to authority. It is a tool for smoothing male ascendance. Go to Full Review Brian Lowry Status News Nov 5
8/10
“The Diplomat” is one of those rare series that seems to have gotten better with each season, largely because of smart casting additions around star Keri Russell. Go to Full Review Rob Owen Pittsburgh Tribune-Review Oct 30
Written and created by “West Wing” veteran Debora Cahn, “The Diplomat” is the best geopolitical thriller made today for any platform. Go to Full Review Read all reviews

Miranda O @RT67890 2d The story is great, but it's the cast that makes it so amazing. The acting is just out of this world, Keri Russell and Rufus Sewell have amazing chemistry, and then in walks David Gyasi to really notch things up! I am really loving it! See more T T @tvenjoy Jul 5 Given the sheer amount of 'crud' on tv these days, I should probably rate it a full five stars. It really is good. Not flawless but really good. See more M B @mbaker21 Jul 1 Sorry, just not enjoying season three. So many things just feel random and out of character. They made the chief of station look weak, they made Kate look like a horny teenager, and so many of the scenes just don’t add any value whatsoever. And we enjoyed both seasons one and two and couldn’t wait to watch season three. Hoping for a strong finish as we have just episode eight left. See more Phil D. @phildub May 3 Debora Cahn & Alex Graves do such a great job on this show I can’t believe it. Binge-worthy and I’ve even rewatched seasons. Cast is always great. I usually can tell which direction a writer is headed. This show goes beyond the imaginable. In part strictly by story. In part by how unpredictable the characters are written. This is the real deal. See more Tom F @RT55173143 Mar 27 Interesting characters make playing the high-stakes game look fun. See more Torben E @Torben Feb 21 Love this show. It's smart, witty and thrilling. With outstanding acting across the board. Keri Russell and Rufus Sewell have amazing chemistry and both deliver fantastic performances. See more Read all reviews
