In Apple TV+’s new espionage thriller, “Prime Target,” created by Steve Thompson, Cambridge University Ph.D. candidate Edward Brooks (Leo Woodall) is on the cusp of uncovering a new way to view prime numbers.

Leo Woodall ('One Day') plays a brilliant graduate student whose work puts him in the crosshairs of a global conspiracy.

A formulaic eight-part thriller, Prime Target revolves around an outstanding but standoffish Cambridge postgrad mathematician called Edward, whose esoteric research into prime numbers sequences inadvertently gives him the tools to access any computer and control the entire digital world.

“Prime Target,” an eight-episode thriller premiering Wednesday on Apple TV+, has the juicy vibe of a novel you might pick up at an airport and rip through in a single flight. It has an outlandish premise, beautiful people, and it ends on a cliffhanger every episode.

Prime Target starts with a captivating concept that blends intellectual puzzles with espionage, but stumbles due to uneven pacing, repetitive exposition, and melodrama that undercuts its potential.

The latest thriller from Apple TV Plus – Prime Target – hasn’t been met with the most glowing reviews. Despite a promising trailer, the series has achieved just 33% on review website Rotten Tomatoes after the first two episodes were made available on the streamer.

With a lead who's out of his depth and an absurd plot, the new Apple TV+ series rarely amounts to anything worthwhile, writes our reviewer.

Leo Woodall stars in a mystery series as a young Cambridge scholar whose theories about prime numbers lead him into a web of international intrigue.
