The year is 2025, and here I am, still very troubled about BBC Sherlock. Now, it's been a while since I wrote any Sherlock meta, but there's something that's been bugging me, and Iād love to get peopleās input and thoughts.
I'm a screenwriterānot a professional one, but an autodidact. I havenāt had anything produced, but I have written several original screenplays. One of the most basic things you learn as a writer in general, and especially in screenwriting, is the concept of the character arc. Itās the art of starting a character off as one thing, taking them through a process of deconstruction or challenge, and letting them emerge as something different.
An exercise I enjoy is watching films or TV shows and analysing a characterās arc. I try to spot hints of how a character will change by the end of an episode, a season, or the entire series. Thatās part of why I particularly love Michael Schurās showsāParks and Recreation, The Office, Brooklyn Nine-Nine. In the Michael Schur universe, character arcs are blatantly laid out for you in the pilot episode. Thereās absolutely no need to philosophize or guess: the characters often state it themselves, or itās clearly expressed through others.
Take, for example, Michael Scott.
In the Office pilot, heās genuinely a terrible boss and a trashcan of a person. But weāre immediately shown his arc via one simple prop: a coffee mug. āWorldās Best Boss.ā Thatās his journeyāto become that boss, if not in the world, then at least in Dunder Mifflin.
Or take Jake Peralta. In B99ās pilot, Terry introduces the squad to Captain Holt with:
āJacob Peralta is my best detective ā he likes putting away bad guys, and he loves solving puzzles. The only puzzle he hasnāt solved⦠is how to grow up.ā
From that alone, you know where Jake is headed. By the end of the show, heāll still be the squadās best detective, but heāll also be a grown-up: a dad, a partner, someone who takes his job seriously and earns the respect of his captain.
In the Parks and Rec original pilot script, Leslie outright declares that sheāll be Americaās first female president. In the aired pilot, the message is softened a bit when Leslie says:
āYou know, government isnāt just a boyās club anymore. Women are everywhere. Itās a great time to be a woman in politics. Hillary Clinton, Sarah Palin, me.ā
There it is: Leslieās arc will involve her rising through the boysā club of American politics and becoming a truly great public servant (and maybeāeven if itās never clearly statedāthe first female president).
So now that Iāve set the scene a bitāunderstanding how a character arc is seeded in a pilotāletās talk about Sherlock.
What are we told about John and Sherlock in the pilot that sets up their character arcs?
Letās start with Sherlock, because that one is spoon-fed to the audienceāby none other than Lestrade. In response to Johnās question, āWhy do you put up with him?ā, Lestrade says:
āBecause Sherlock Holmes is a great man. And I think, one day, if weāre very, very lucky, he might even be a good one.ā
Thatās it. Thatās Sherlockās arc. The writers are telling us outright: hereās a brilliant but emotionally disconnected man. And the journey ahead of him isnāt about intellect, but about goodness. About connection, humanity, compassion. Becoming not just great, but good. And, if I might add a bit of Johnlock, not just to anyoneābut through John, with John, and ultimately because of John.
Now, Johnās arc is a little less obvious in my opinion, though just as importantāand itās given to us by Mycroft, who says:
āYouāre not haunted by the war, Dr. Watsonāyou miss it.ā
To me, this says: here is a traumatized soldier who never fully came back from war. Heās unmoored, disconnected, half-alive. "Nothing ever happens to me." And the arc we should expect? A man who, over time, things happen to him and he finds peace. Who finds meaning in his civilian lifeāback in London, in friendship, in purpose, in (perhaps) love. Who, by the end of the series, no longer misses the war.
Thatās the setup. Thatās what we were promised. Or at the very least, that's what I feel I was promised.
Only⦠whatever I feel was promised never actually happened.
In fact, Sherlock ends up delivering the complete opposite. In Seasons 3 and 4, the show leans into Sherlock as a mythic, near-supernatural figureāthe āadult who never was a child.ā This directly contradicts the idea of humanising him. The sudden introduction of Eurus shifts the focus from internal growth to external spectacle. His evolution becomes a reaction to trauma, not a conscious transformation toward goodness.
By the end of The Lying Detective, Sherlock is still fundamentally isolated and emotionally unavailable. Despite supposedly learning to āconnect,ā he doesnāt share emotionally in any meaningful wayānot with John, not with Eurus, not with Molly. The āI love youā scene is a puzzle to be solved, not a moment of genuine vulnerability. John and Sherlockās confrontation at the end of TLD achieves absolutely nothing in terms of their openness or intimacy.
Sherlock's arcāof becoming a good manāis never achieved. Now, we can argue about that, because Sherlock is a softie at times. He is kind. And donāt get me wrongāwhen Michael Scott leaves Dunder Mifflin, heās by no means a perfect boss. But heās loved by Pam, heās missed by Jim, and the Dunder Mifflin team has learned to respect him in their own way.
I know some of you are itching to shout that Sherlock's arc won't be complete without S5 and in theory, I agree! But! Lest we forget, Lestradeās āprophecyā (supposedly) comes full circle in The Final Problem:
"No, heās better than that. Heās a good one."
This, supposedly, is the great moment of The Payoff. Here stands Sherlock, A Good Manā¢.
Which⦠always makes me scratch my head.
Is he, Lestrade? Really? What is it, exactly, in those last few days that convinces you of that? What moment between The Six Thatchers and The Final Problem gives you that impression?
Nothing. Reallyānothing. This, for me, is absolutely zero character arc payoff.
Now, what about Johnāwho was supposed to come back from the war, or at most, get his adrenaline kicks chasing criminals with Sherlock through the streets of London?
Maryās death completely hijacks John's growth as a character. Rather than showing John finding stability in his marriage and family (or with Sherlock, in whatever shape that takes), the show strips it all away. And worse, it distances him from Sherlock once moreāthrowing him into another spiral of guilt and rage, effectively rebooting his trauma rather than resolving it.
The finale gives John no closure. We donāt know where John is emotionally by the end of The Final Problem. Is he at peace? Are we supposed to believe that a happy montage fixes everything? Does he still crave danger? Does he still feel violent impulses toward Sherlock?
I canāt even begin to think when or how Mycroftās seed of Johnās arcāāyou miss the warāācomes full circle in The Final Problem. Unlike Lestradeās line about Sherlock, thereās nothing that brings that theme to any kind of resolution. Itās as though Moftiss forgot to give John a conclusion altogether.
Iāve sometimes wondered if Sherlockās words to John in TLDāāWe might all just be humanāāwere meant to gesture at Johnās arc. But⦠why would it?
John never struggled to understand that he was human. That wasnāt his arc. That wasnāt his flaw. He knew he was human and he always craved for that humanity from Sherlock. So what, then, was that line supposed to resolve?
I can play devil's advocate here. Character arcs can be negative. A character doesn't always have to have a happy ending, and had Moftiss boldly done that, I would have appreciated it. But they hadn't- they give us a weird ass montage with John and Sherlock happily giggling at Rosie. It's just feels like there's absolutely no conclusion for John, whether negative or positive.
Adding insult to injury, Maryās 'speech' during the final montage is actually dismissive of their "growth":
āThere are two men sitting arguing in a scruffy flat. Like theyāve always been there, and always will.ā
Which completely negates the idea that theyāve changed. At that point, theyāre not like theyāve always been. John's quite possibly worse than when we met him.
āThe best and wisest men I have ever known.ā
Againāwhatās with the John erasure? Letās say, for the sake of argument, Sherlock is better nowāwhat makes him wise? And Johnās arc was never about becoming wise, so what does that even mean?
āMy Baker Street boys.ā
Are they? Are they still the Baker Street boys (I hate that nickname)? Weāre never told if John and Rosie move back in. In fact, in a Q&A Moftiss declare John does not return to Baker Street.
And thatās just it, isnāt it?
The Final Problem finale doesnāt fail because it was mysterious or ambiguous or hilariously bad or tragic. It fails because it abandons the emotional contract it made with its viewers in the very first episode. It forgets the arcs it promised, the healing it hinted at, the people these characters were meant to become.
We didn't need a happy ending. But we did need a real one.
