Person of Interest (Seasons 1–5)

Person of Interest (2011–2016) is a CBS sci-fi crime drama you can watch online on iFILM — 5 seasons, 103 episodes, created by Jonathan Nolan and produced by Bad Robot and Warner Bros. Television. Jim Caviezel plays John Reese, a former CIA operative presumed dead; Michael Emerson plays Harold Finch, the reclusive billionaire who built a mass-surveillance AI for the government.

The Machine monitors every camera feed in New York and flags threats before they happen — but it only outputs social security numbers. Finch recruits Reese to act on those numbers, operating completely off the books. Detective Fusco runs interference from inside the NYPD. Agent Shaw joins later, bringing a different kind of edge. As the seasons progress, a rival AI enters the picture and the stakes shift from street-level crime to something much larger.

Nolan developed the show before Westworld, and the same questions about machine intelligence and surveillance run through every season. The episodic cases keep it grounded; the long-arc conspiracy keeps it moving. Stream all seasons of Person of Interest online on iFILM.
