Best TV thrillers of all time

Severance▲ Rising

The elevator ding that splits Mark into 'innie' and 'outie' is one of the most unsettling high-concept openings TV has ever pulled off, turning corporate drudgery into full-blown existential horror. It made water coolers argue about consciousness and consent instead of just plot twists, proving prestige sci-fi could be both a puzzle box and a gut-punch. Its clinical dread and Lumon's smiling menace earn it a spot among the genre's most original nerve-shredders.

X-Files▲ Rising

Mulder and Scully in a darkened basement office, flashlight beams cutting through fog, invented the modern conspiracy thriller template that everything from Fringe to True Detective still borrows from. 'The truth is out there' became a cultural mantra, and the show's mix of monster-of-the-week dread with a slow-burn mythology arc taught television how to sustain paranoia over years, not episodes. Its DNA runs through nearly every serialized thriller that followed, making it foundational rather than merely influential.

Slow Horses▲ Rising

Gary Oldman's Jackson Lamb, flatulent and cruel and somehow the smartest man in every room, redefined what a spy thriller protagonist could look like — a far cry from clean-cut Bond fantasy. The show's willingness to kill major characters in shocking, almost throwaway fashion (that Regent's Park sequence) signaled it wasn't playing by genre-safe rules. It's the rare le Carré-adjacent thriller that's genuinely funny without ever losing its teeth, earning cult devotion season after season.

Squid Game▼ Falling

Hundreds of debt-ridden players in green tracksuits freezing mid-Red-Light-Green-Light as a giant doll's sensors sweep the field is now one of the most parodied images in television history. The show weaponized childhood games into a brutal indictment of capitalism and became Netflix's most-watched series ever, proving a Korean-language thriller could dominate global culture overnight. Its shocking, unsentimental violence and class-rage core make it the defining thriller of the streaming era.

Money Heist▼ Falling

The image of red jumpsuits and Dalí masks marching in unison turned a Spanish heist drama into a global streaming phenomenon and a literal protest symbol from Chile to Lebanon. 'Bella Ciao' became an unofficial anthem of resistance, proof that a show about outsmarting a national bank could tap into something bigger than its plot. Its operatic twists and Professor's five-steps-ahead plotting made it Netflix's first true worldwide crossover thriller.
