Origin stories are a tricky business, especially when the character in question has been rebooted, modernized, and deconstructed more times than we can count. But Guy Ritchie's Young Sherlock takes a fresh approach: strip away the pipe, the legend, and the infallible logic, and show us the messy, brilliant young man behind the myth. The result? A detective saga that's already a streaming hit on Prime Video.
Set at Oxford University, the series follows a 19-year-old Sherlock Holmes (Hero Fiennes Tiffin) who is raw, rebellious, and far from the disciplined detective we know. Inspired by Andrew Lane's Young Sherlock Holmes book series, the show was developed by Peter Harness and Guy Ritchie, with Ritchie directing two episodes. It premiered on Prime Video in March 2026 and has already been renewed for a second season.
The cast is stacked with talent. Hero Fiennes Tiffin (After, The Woman King) leads as Sherlock, while Dónal Finn (The Wheel of Time) plays James Moriarty. Zine Tseng (3 Body Problem) appears as Princess Gulun Shou'an, and Joseph Fiennes (The Handmaid's Tale) and Natascha McElhone (The Truman Show) portray Sherlock's parents, Silas and Cordelia Holmes. Max Irons (The White Queen) plays Mycroft Holmes, and Colin Firth (The King's Speech) takes on a juicy, unspoiled role that fans are already buzzing about.
Critics have been universally glowing. CBR's Nicholas Brooks praised the show's approach, noting that "the stakes are high, the action is top-notch, and death is always right around the corner." ScreenRant's Ben Gibbons called it "an incredibly clever and imaginative retelling of a classic story that manages to preserve the best aspects of the source material." Collider's Therese Lacson added that while Young Sherlock may not be faithful to Arthur Conan Doyle's works, it more than compensates with sheer entertainment value.
If you're a fan of Guy Ritchie's signature style—fast-paced action, sharp dialogue, and a gritty yet stylish aesthetic—this series delivers. It also fits neatly alongside other Prime Video crime dramas like Bosch, which set the gold standard for modern crime storytelling.

Young Sherlock is streaming now on Prime Video. With its blend of mystery, action, and character-driven drama, it's no surprise the series has already earned a second season. Whether you're a longtime Sherlock fan or new to the detective's world, this origin story is worth your time.
