Prime Video’s Young Sherlock wants to be the origin story everyone expected from Sherlock Holmes. It gets there by making its young hero a raw, unfiltered troublemaker rather than a disciplined genius. That choice shapes everything about the show, for better and for worse.

The Premise
Sherlock Holmes is a 19-year-old student at Oxford University, still finding his way toward the detective he will become. A murder at the university puts his freedom at risk, and he sets out to solve his first murder mystery. That case leads him to a global conspiracy, one that changes his life forever.
The premise is simple and effective. It takes the familiar Holmes setup — a crime, a chase, a larger scheme — and roots it in a specific place and time. Oxford gives the story a sense of place that a standard “young detective” show often lacks.
The Cast
Hero Fiennes Tiffin plays Holmes as a restless, awkward young man. He is not the polished figure audiences know from later stories. That rawness is the point.
Dónal Finn plays James Moriarty, and Zine Tseng plays Princess Gulun Shou’an. Natascha McElhone plays Cordelia Holmes, and Max Irons plays Mycroft Holmes. Together, they fill out the world around Holmes without overshadowing him.
The Story’s Weak Points
The pacing drags in stretches. Some episodes spend too much time establishing the conspiracy without letting the investigation move forward. The show also leans heavily on exposition, with Holmes explaining the case to himself as often as he explains it to others.
These are minor complaints against a solid core. The show knows what it wants to do and mostly does it well.
What Works
- The setting at Oxford grounds the story in a specific, detailed world.
- The central mystery is genuinely engaging.
- Fiennes Tiffin carries the show with a convincing performance.
- The supporting cast gives him room to breathe.
Where It Falls Short
The show is at its best when it lets Holmes be a young man learning on the fly. It is less successful when it tries to explain everything to the audience. Some episodes feel padded, and the final stretch rushes through developments that could have used more space.
The Verdict
Young Sherlock is a promising start for a series that wants to grow into something bigger. It respects the source material while making its own mark. The flaws are real, but they are small compared to what the show gets right.
6.5 out of 10.
That score reflects a show that knows its strengths and its limits. It is worth watching for the premise and the performances, even when the execution stumbles.
