David Bianculli NPR 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. Oct 31, 2025 Full Review James Jackson The Times (UK) 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. Rated: 4/5 Oct 17, 2025 Full Review Sam Adams Slate It’s smart, except when it’s dumb. Oct 17, 2025 Full Review Yamily Habib LatinaMedia.Co 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. Nov 11, 2025 Full Review Brian Lowry Status News “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. Rated: 8/10 Nov 5, 2025 Full Review Rob Owen Pittsburgh Tribune-Review Written and created by “West Wing” veteran Debora Cahn, “The Diplomat” is the best geopolitical thriller made today for any platform.

Bowser H A masterclass on how to annihilate a protagonist’s appeal in a single season. The show actually made me angry. Rated 0.5 out of 5 stars 11/13/25 Full Review Horvath A A good political drama ruined with needless and boring couple drama. Its a shame. Rated 0.5 out of 5 stars 11/13/25 Full Review Dave B Season 3 continues this excellent series. I don't think I've ever connected so well with a television/cinema character as I do with Keri Russel's Kate. Her face communicates more than words so often. When she's thinking about Callum, there's little more than a twinkle in her eye, and you know she's fallen hard for him. Then the plot, it's fantastic, the first half of season three is highly relationship oriented, then the submarine comes in on top of that setting. I can't stop watching. Please make sure season 4 lives up to the first three... Rated 4.5 out of 5 stars 11/13/25 Full Review YOCHABEL S So well written and full of incredible character interactions. I wish it had 20 episodes. Rated 5 out of 5 stars 11/12/25 Full Review ARDIT M From a high level action drama filled with assassination plots, world affairs at the highest level, turned into a desperate housewife way over her head! Unlike seasons 1 and 2, season 3 is about the ‘tantrums’ of a wife that is overly ambitious and wants to be in every possible turmoil just to showcase her worth! Not that she is the most qualified, gives the best solutions, so that one may cheer for her input, it is more of a drama of being embarrassed at the highest level of world affairs. Boring and disaapointing, hope season 4, if there is one, is more of a reincarnation of season 1 and 2 and pretends there was no season 3. Rated 1 out of 5 stars 11/08/25 Full Review Dave F Decided to re-subscribe to Netflix so I could watch season three. What a disappointment. I’m through six episodes and I’m forcing myself to get through the end of the season. I must be a masochist. The only bright spot is the chemistry between Janney and Whitford. I could watch those two on screen all day. Rated 1.5 out of 5 stars 11/08/25 Full Review Read all reviews
