The 50 Best Spy TV Shows Ever

Deciding which series are worthy of inclusion on a list of the best spy shows and streaming series ever is a matter of mystery itself.

With its propensity for disguises, double-crosses, and surveillance, FX’s Cold War–era drama The Americans, is certainly about spies. But the series — which has a 96% series-level Tomatometer score, every season of which is Certified Fresh (including one 100% CF season), and is regarded by critics as one of the greatest shows in this Golden Age of Television — is also about marriage, parenting, and history’s winning side’s ability to whitewash facts. Should it receive a lower ranking on our ultimate spy show list than a classic like CBS’s Mission: Impossible? Also of note: They both have catchy theme songs.

Where should a complicated sci-fi caper like Starz’s Counterpart stand? The series, which returns for season 2 on December 9, finished off its first season with one of those rare, perfect 100% Certified Fresh Tomatometer scores. It stars J.K. Simmons as both a mild-mannered bureaucratic pencil pusher and his aggro alt-universe counterpart, who hunt dangerous reality-hopping spies.

The espionage stories of John le Carré have also had televised adaptations. Le Carré’s The Night Manager (featuring one of Britain’s top Toms) and, most recently, The Little Drummer Girl both aired on AMC, are Certified Fresh at 90% on the Tomatometer, and rank high on our spy series list.

Spycraft can also be quite funny, as in Mel Brooks and Buck Henry’s beloved Get Smart, which ran on NBC and CBS in the late ’60s, and the long-running animated FX comedy Archer, which has a 93% Tomatometer score.

We considered more than Tomatometer scores to finalize our spy show ranking, however; we also looked at variables like how many seasons each series has, how each of those seasons scored, how many reviews determined those scores, and whether those seasons were Certified Fresh, We looked at other reputable media lists of top spy series to help gauge where to place some classic series without enough reviews to register a Tomatometer score, and then applied a dose of editorial discretion to break some ties and rank some titles based on their cultural resonance.

Check out Rotten Tomatoes’ list of best spy shows ever before it self destructs in three … two … just kidding. Like the FBI’s most wanted list, we’ll keep updating this dossier as more information becomes available.
