Young Sherlock Review: Prime Video’s Wild New Origin Story for the Legendary Detective

Two men in brown hats and vintage attire stand beside a horse saddle, exchanging serious looks, with a blurred green background.

Prime Video’s Young Sherlock has officially landed, and it’s about as far from a dusty Victorian library as you can get without adding a laser show. This isn't your grandfather's detective; this is a 19-year-old Sherlock Holmes who looks like he’s perpetually ten minutes away from starting a mosh pit at an Oxford pub.



A Sherlock for the TikTok Generation?

Hero Fiennes Tiffin takes the lead as the titular genius, and while the cheekbones are doing a lot of the heavy lifting, he manages to sell a version of Sherlock that is equal parts brilliant and insufferable. Set against a backdrop that feels more "steampunk-meets-MMA" than traditional Arthur Conan Doyle, the series kicks off with a mystery at Oxford that forces Sherlock to trade his textbooks for a magnifying glass and occasionally a pair of brass knuckles.


The most jarring (and honestly, refreshing) departure? The complete absence of Dr. Watson. Instead, the emotional core of the show shifts to Sherlock’s relationship with his family and, most intriguingly, a young, surprisingly charismatic James Moriarty, played with scene-stealing intensity by Dónal Finn. Watching the two future nemeses wander through Sherlock's "Mind Palace" together—a visual effect that feels like a fever dream directed by a frantic cinematographer is easily the highlight of the season.


Style Over Substance? Maybe, But What Style!

Guy Ritchie’s signature "fizzing" energy is all over this production. From the punk-rock soundtrack to the kinetic, whip-fast editing during deduction sequences, the show moves at a breakneck speed. Is the logic always sound? Absolutely not. There are moments where Sherlock’s "deduction gymnastics" feel less like genius and more like the writers throwing darts at a board of coincidences.


However, the supporting cast keeps the ship upright. Colin Firth is a comedic delight as the blustering Sir Bucephalus Hodge, and the casting of Joseph Fiennes and Natascha McElhone as Sherlock’s parents adds a layer of pedigree that the show’s wilder moments desperately need.


The Verdict

Young Sherlock is a loud, stylish, and occasionally "dumb-fun" reimagining that will likely infuriate purists while giving everyone else a reason to keep their Prime subscription active. It leans into its own absurdity with such confidence that you almost forget you're watching a detective show and start believing you're watching a Victorian superhero origin story.


Whether you're here for the mystery or just for Dónal Finn’s cheeky grins, there’s no denying that this version of Baker Street’s finest is at least trying something new. Grab your leather trench coat and prepare for a binge; the game is afoot, and it’s never been this noisy.
