I just watched the first episodes of Young Sherlock, and while it is still far too early for a full review, the show left me with enough impressions to justify a few reflections. Sherlock Holmes has been adapted so many times that any new interpretation inevitably invites comparison. Even a promising first episode must stand in the shadow of more than a century of adaptations.
The premise of the series is simple but potentially very interesting. Instead of presenting the already legendary consulting detective, the show explores Sherlock during his youth, before he becomes the figure we recognize from the stories of Arthur Conan Doyle.
The series follows a teenage Sherlock navigating school, friendships, and the first mysteries that begin shaping his analytical mind. It is loosely inspired by the Young Sherlock Holmes, which similarly imagine Holmes’ formative years and early adventures.
In this version, the focus is less on the famous detective solving intricate cases and more on the experiences that might explain how the famously detached observer of human behavior eventually came to see the world the way he does.
A Holmes Who Has Not Yet Become Holmes
One of the more interesting aspects of the show is that Sherlock is not yet the fully formed character we expect. The cold rationality and emotional distance that define the adult Holmes are only beginning to emerge.
Instead we see a young man who is still forming his worldview, still testing his abilities, and still figuring out how he fits into the world around him.
Among the characters around him is one played by Dónal Finn, whom many viewers will recognize as Mat Cauthon in The Wheel of Time. Seeing him appear here in a very different role was interesting. The character serves as a companion and foil to Sherlock, and I can easily imagine the two as different sides of the same coin: instinct and improvisation balanced against Sherlock’s emerging analytical mindset.
If the series continues for multiple seasons, it would not be surprising if we eventually see the gradual path toward the more solitary and intense figure that readers know from the original stories.
The Shadow of Moriarty
Perhaps the most intriguing narrative choice in Young Sherlock is the presence of James Moriarty not as an enemy, but as a friend.
Anyone familiar with the original Holmes stories knows where this relationship ultimately leads. Moriarty is famously described by Holmes as the “Napoleon of Crime,” the brilliant mastermind who stands as his intellectual equal and ultimate adversary.
Seeing the two characters as companions in their youth introduces a strong element of dramatic irony. The audience already knows the eventual outcome: these two minds, once aligned, will ultimately stand in opposition to one another.
This raises an interesting question about the direction of the series. Will the show gradually depict the events that push Moriarty toward criminality and Holmes toward the role of the detective determined to stop him? Or will it diverge more radically from the traditional mythology and chart a different path entirely?
If the writers choose the former, the series could develop an almost tragic dimension. Watching a friendship slowly fracture under the weight of ambition, ideology, or circumstance would give the Holmes–Moriarty rivalry a far more personal dimension than most adaptations have explored.
And in some ways, that might be the most interesting idea in the entire premise: not simply the origin of Sherlock Holmes the detective, but the origin of the one mind capable of opposing him.
Colin Firth Appears — and Looks Very Different
Another unexpected appearance in the series is Colin Firth, here playing Bucephalus Hodge, sporting a pair of rather impressive Victorian sideburns. It was slightly surprising to see him again in such a role.
For many viewers he will always be closely associated with his portrayal of Mr. Darcy in Pride and Prejudice, one of the most beloved adaptations of Jane Austen. That performance became so iconic that it shaped how the character is imagined even decades later.
Personally, the last time I distinctly remember seeing him was in Tinker Tailor Soldier Spy, though he has of course appeared in many films since then.
The Importance of Setting
One of the things I appreciated most about Young Sherlock is its decision to place the story firmly in a historical setting. Sherlock Holmes feels deeply tied to Victorian England. The foggy streets, the early forensic sciences, and the social structures of the time are all part of what makes the stories work.
This is also why modernized adaptations sometimes feel slightly off, even when they are very well made.
For example, the BBC series Sherlock, starring Benedict Cumberbatch as Holmes and Martin Freeman as Watson, was undeniably excellent television. The first season in particular captured the excitement and intellectual playfulness of the character extremely well.
Yet the modern setting never felt entirely natural to me. Holmes operating in a world of smartphones, GPS, and digital surveillance inevitably changes the nature of detective work.
The Cinematic Holmes
The film adaptations starring Robert Downey Jr. as Holmes and Jude Law as Watson — beginning with Sherlock Holmes — arguably captured the atmosphere of the period more successfully.
Those films kept the Victorian setting but leaned heavily into a more action-oriented interpretation of the characters. Holmes became something closer to a Victorian action hero, combining deduction with bare-knuckle fighting and elaborate physical stunts.
The interpretation was unusual, but the films were undeniably entertaining.
A New Angle on a Familiar Character
What Young Sherlock attempts is something slightly different again: it asks what Holmes might have been like before the legend. Before Watson. Before Baker Street. Before the famous cases.
This approach opens up interesting possibilities. If handled well, it could provide a believable psychological bridge between an ordinary young man and the brilliant but emotionally distant detective readers know from the stories.
For now, it is still too early to judge whether the series will fully succeed. First impressions are promising, but Holmes adaptations have a long history of starting strong before struggling to maintain momentum.
Still, the idea of exploring Sherlock Holmes’ formative years — and perhaps the origins of his relationship with Moriarty — is an intriguing one. If the show manages to balance mystery, character development, and historical atmosphere, it could become a worthy addition to the long tradition of Holmes adaptations.
I will likely return to the series once the full season has aired — and perhaps write a more complete review then.
