If you thought you'd seen every possible version of Sherlock Holmes, think again. Guy Ritchie, who previously directed Robert Downey Jr. in two Sherlock films, has returned to the character with a fresh twist on Prime Video. The series Young Sherlock is quietly becoming one of the platform's most compelling detective shows, and it's easy to see why.
Based on Andrew Lane's young adult thriller novels, the eight-episode prequel follows a 19-year-old Sherlock Holmes at Oxford University. Long before he encounters Baskerville or any studies in scarlet, this series explores the foundational chapter of one of literature's greatest detectives. It also introduces key villains, including a young James Moriarty, in a way that feels entirely new.
A Fresh Take on a Beloved Character
By setting the story during Sherlock's teenage years, Young Sherlock avoids direct comparisons to past portrayals. Hero Fiennes Tiffin steps into the role with a performance that blends the character's signature brilliance with youthful vulnerability. As noted in a Collider review, Tiffin finds a sweet spot: "He's not nearly as cold as Benedict Cumberbatch, he's not as erratic as Jonny Lee Miller, he's obviously not as well-balanced or as mature as Henry Cavill, and he certainly can't throw a punch like Robert Downey Jr.'s Sherlock."
The series also gives viewers a compelling origin story, showing the motivations, betrayals, and murders that shape Sherlock into the world-renowned detective he becomes. Similarly, James Moriarty (Dónal Finn) is portrayed as a teenager, and surprisingly, he and Sherlock are friends. They work together to solve crimes, relying on each other as partners and confidants. This dynamic makes Moriarty's inevitable turn to evil all the more devastating.
Guy Ritchie's Signature Style Meets a Stellar Cast
Ritchie's electric direction is on full display, with kinetic action scenes, staccato dialogue, and frenetic camera work that keeps viewers on the edge of their seats. The pacing is perfect for this youthful version of Sherlock, slotting seamlessly into a story that keeps its characters on their toes. The series has already snagged the #1 spot on Prime Video worldwide and earned an 84% critics' score on Rotten Tomatoes, with an 83% audience score.
The cast is equally impressive. Tiffin delivers what one review calls a "career-defining performance," while Finn brings unbridled charm to his role as the soon-to-be villain. Zine Tseng plays visiting Chinese Princess Shou'an, Colin Firth portrays Oxford Professor Sir Bucephalus Hodge, Joseph Fiennes is Silas Holmes, Max Irons plays Mycroft Holmes, and Natascha McElhone appears as Cordelia Holmes. This ensemble elevates the series beyond a typical detective show.
For fans of detective thrillers, Young Sherlock is a must-watch.
