Young Sherlock Hits No. 1 on Prime Video — But Critics and Purists Are Not Sharing the Same Case File
Guy Ritchie returned to Baker Street last week with eight episodes, a record-shattering trailer, and a version of Sherlock Holmes that gets punched in the face three times before the first episode ends. The audience loved it. Critics are split down the middle. And the debate is loud.
The Numbers Are Impossible to Ignore
Young Sherlock premiered March 4 on Prime Video with all eight episodes available at once and within days claimed the No. 1 spot worldwide on the platform. The official trailer accumulated 223 million YouTube views in its first seven days — shattering existing streaming series records.
On Rotten Tomatoes, the series holds an 84% critics score alongside an 85% audience score, earning Certified Fresh status that is described as unprecedented for a Sherlock Holmes origin story. For a show critics are calling a mismatch, those are unusually strong numbers.
What Ritchie Actually Built
Set in 1871, the series follows a 19-year-old Sherlock Holmes at Oxford — raw, unfiltered, and lacking the discipline that defines the finished detective readers know. Hero Fiennes Tiffin, nephew of Ralph and Joseph Fiennes, takes the lead. The surrounding cast includes Dónal Finn as a young James Moriarty, Joseph Fiennes as Sherlock's father Silas, Natascha McElhone as his mother Cordelia, Max Irons as Mycroft, and Colin Firth in a supporting role.
The series is essentially an origin story for both Holmes and Moriarty, with the two developing a friendship at Oxford before Sherlock links a string of murders to a hidden family tragedy — specifically, the faked death of a younger sister that tore the Holmes family apart and turned his own father into his first nemesis. It is a sharp structural choice, grounding a globe-trotting conspiracy in something personal.
Filming ran from July 2024 through February 2025, with locations spanning Bristol, Cardiff, Seville, Cádiz, and Jerez.
The Case Against
The critical dissent is specific and consistent. What die-hard Holmes fans love about the character — his cerebral methods, eccentricities, and serene rationality — sits at direct odds with Ritchie's instinct for bare-knuckle brawling, ramshackle plots, and frantic crosscutting timed to heavy bass-driven music cues.
Slate argued Fiennes Tiffin is miscast — more suited to a cruel, arrogant rich kid than the ascetic Holmes of legend — and noted the anachronistic soundtrack, which leans heavily on 1990s indie and folk rock with a Kasabian track from 2011 anchoring the title sequence. The show, in that reading, feels like Ritchie wishing he were making Young James Bond but settling for a public domain property.
One critic put it plainly: the project missed its window by a decade. Had it arrived before 2015, it wouldn't feel like a director straining to stay relevant — it would have felt like an event.
The Case For
Audiences pushed back, hard. Variety called it sensational, praising Episode 5 in particular as riveting. Common Sense Media landed in the middle, calling it fun, fast-paced, and clever — elevated by Ritchie's signature action shots and camera cuts.
ComicBook.com argued the finale, which draws direct parallels to Conan Doyle's "The Adventure of the Final Problem," demonstrates remarkable skill and adds genuine depth to the 133-year-old source material.
Dónal Finn's performance as young Moriarty has emerged as a consistent bright spot across even negative reviews. His portrayal creates an electric tension with Fiennes Tiffin that critics compare to legendary cat-and-mouse narratives, with the two characters' opposing moral codes building beneath their early friendship.
What Comes Next
The Young Sherlock launch is happening alongside movement on a separate Ritchie-adjacent Holmes project. Sherlock Holmes 3 was reported back in development as of January 30, 2026, with Dexter Fletcher tapped to direct and Robert Downey Jr. and Jude Law expected to return — though Young Sherlock carries no official connection to those films.
ComicBook.com concluded its review with a direct call: "We can only hope Guy Ritchie gets a chance to continue this story."
