What kind of watch this is
Young Sherlock is a 2026 action-adventure mystery that watches a detective before he earns the title. It is for anyone who prefers the chaos of the first mistake over the polish of the final solution. The series runs 9 hours across 2 seasons and 11 episodes, a commitment that asks you to sit with a character who is loud, flawed, and not quite ready for the scale of his own life. It is a fast-paced watch for fans who want the origin story to feel like a rough draft rather than a polished legend.
What the critics said
Rotten Tomatoes sits at 84% across 50 reviews, with an average of 7.1 out of 10. Metacritic lands on 65 out of 100, labeling the reception generally favorable. The consensus praises Guy Ritchie’s sly style and liberal adaptation of the source material. Tiffin drew specific praise for his Sherlock Holmes, though some felt Finn’s Moriarty stole the spotlight. A competent adaptation that knows its own rules.
How it did with audiences
On TMDB, users give it a 7.8. Without box office data to measure mass appeal, the rating stands alone as the primary metric. It tells us the film worked for those who sat down to watch it, which is the only audience that actually matters for a single viewing.
