“The Final Problem” is perhaps aptly named as I am seemingly in the minority of people who were disappointed with this episode which could potentially spell the end of the amazing series.
Warning: spoilers ahead!
Episode 2 left is with two great cliffhangers:
1. What is the story of The secret Holmes sister Eurus?
2. What will be the outcome of John getting shot?
How these questions are answered is the real measuring stick of this episode’s success…
The show opens with a sequence where Mycroft is scared while watching an old home movie. The entire scene turns out to be a trick played by Sherlock after which he reveals that he knows that their secret sister was incarcerated and Watson reveals that he was shot with a tranquilizer. It felt completely unnecessary and worse, like we were deceived in the last episode and robbed of seeing Sherlock’s discovery of the sister.
Sherlock, Watson and Mycroft decide to go visit the prison where their sister is supposed to be captive. For some reason, even though Mycroft seems to have sway with the institution – they decide to commandeer a ship and disguise themselves to get themselves into the penitentiary.
Their plan backfires as they learn – in a pretty cool way – that Eurus is actually in charge of the prison. She apparently has the power to “reprogram” people. This is a really interesting concept with a ton of potential… although it also raises several questions that the show avoided such as: if she has this ability – and already escaped, why would she attempt to murder them via a grenade attached to a drone, and subsequently go back to the prison just to wait for them to show up?
We also learn that Eurus also had interactions with Moriarty, but I think they messed this opportunity up as well. This would have been a great explanation for Moriarty’s obsession with Sherlock. But instead they decided that he already had the obsession and just got additional assistance/information from Eurus. Feels like a missed opportunity.
Having enslaved Sherlock, Watson and Mycroft, Euros decides to set up a series of riddles for them to solve. In order to motivate them into action she dangles an impending plane crash over them, which they can help avert by solving the crimes.
However the riddles don’t really add up to anything related to the plane conundrum, nor do they really relate to much at all in the plot. It is as if more than half of the episode was one giant red herring.
By the end of the series of events Sherlock throws a wrench into Eurus’ scheme and she is forced to knock them unconscious (for a second time).
This time when Sherlock wakes up he is in a strange room while Watson is chained to the bottom of a well and Mycroft is nowhere to be found. This time the threat is that Sherlock must solve the mystery of his dog Redbeard in order to save both John and the doomed airplane.
The “answer” to this mystery kind of comes out of nowhere. It’s not one of those mysteries where clues were offered along the way, rather it was a case of Sherlock having the wrong facts due to having been reprogrammed by his sister years ago.
The final answer to the mystery is a cipher hidden among grave stones – which is a ridiculously long message that ultimately tells Sherlock to go to Eurus’ bedroom, where he SHOCKER… finds Eurus – who somehow was sane enough to leave this bizarre clue for Sherlock and yet is so insane that the entire plane situation existed only in her mind (yet somehow this figment of her imagination communicated with Sherlock in yet another unexplained plot hole).
This was all very disappointing, perhaps the most disappointing show of the entire series. But the ending made it even worse. Trying to wrap everything up they found yet another video from Mary where she touts Sherlock and Watson as great adventurers and then it has the audacity to finish with them running towards the camera in a shot that reminded me of the ending of Batman Forever.
I literally lost sleep after this. My mind was arguing between thinking “I hope this isn’t how they end the show” and “where else is there for this show to go from here?”
That is the great mystery.
Here’s a video review that share’s my sentiments:
