It has been a few days since I watched Doctor Who ‘Extremis’. On first viewing I was gripped and thoroughly engrossed with what was presented. However, the more I’ve thought about it, the more the episode falls apart…
The Simulation
Initially I was impressed with this revelation, largely because I didn’t see it coming. My initial thoughts were of the Matrix or Deep Thought from ‘The Hitchhikers Guide to the Galaxy’. Unfortunately buying into the concept exposes the flaws of it.
Firstly, this simulation is so intricate that not only can it account for the rogue elements of a Time Lord and his assistant Nardole, but also details such as the inside of the TARDIS. Similarly, this simulation is so advanced that it can legislate for The Doctor going blind. What makes this even less likely is that these events occurred not only off-world but also in the far future. If an alien species can create technology that advanced why would they need to rehearse an invasion? In fact, what was it that was frightening about the Monks?

The Monks
Visually the Monks were very striking. When the distorted facial features were revealed it was a strong moment. But other than emerging from the portals which they presumably opened, they did nothing. Absolutely nothing.
Consider when we were introduced to the Silence who, let’s be frank, are not a million miles removed from this new creation. In a scene in the Ladies toilet (The Impossible Astronaut, 2011) the quirk of forgetting the creatures when you were no longer looking at them was introduced. The alien then murdered an innocent woman in front of Amy Pond. In contrast the Monks ambled after a fleeing Doctor and did some pointing. There wasn’t actually anything which they did that was fear inducing. Even they way they spoke was clumsy. The mouth opened and a voice was emitted. Fine. Worked well for the Cybermen. But then there were moments when the jaw did move whilst the voice was projected. Pick one! Plus they fell into the classic Doctor Who monster flaw; utterly inept in a chase situation. Even a Doctor struggling to see managed to elude them.

The Doctor
Again my initial reaction was how refreshing it was to see The Doctor being vulnerable. However the more I’ve considered it, the more illogical it became. In the past we have seen the Time Lord use some of his regeneration energy. Once it was used to recharge a fuel cell (Age of Steel, 2005) and on another occasion this energy was donated to Davros (The Witch’s Familiar, 2015). And yet this ability has been forgotten. Instead a new tool was introduced with some nonsense about borrowing from a future regeneration. The Doctor’s blindness could have been implied at the conclusion of ‘Oxygen’ then the simulation revelation could’ve been further reinforced by the bombshell that he was indeed still blind in our reality. Instead this simulation was, somehow, able to anticipate The Doctor going blind.
Nardole
Assisting The Doctor is of course Nardole and we had a hint that he’d been sent by River Song. He even claims and behaves like a bad ass, elevating his character above that of comic foil. Unfortunately seconds later he shrieks and undoes all of that positive work immediately. His character is just so inconsistent. Also we can assume that he isn’t human and is slightly robotic but yet the Monks were able to legislate for his presence and fit him within the software subroutines. Once again his place within the simulation program lacked credibility.
The Pope
The preview scene of the Pope interrupting Bill’s date typifies the episode. It is clumsy. Firstly, there’s a touching moment where Penny begins to reveal her nerves about her sexuality. Bill shapes up to help her through it in the caring manner that we’ve come to expect of her. To ruin this poignant moment is, of all people, the Pope. The way Penny reacted, not thinking it was a foolish student housemate but instead recognising the real Pontif was telling. This implied a history of Catholicism but that was not clear. Instead the scene degenerates into comedy but falls flat on it’s face.
Missy
Another guest appearance in the episode was a returning Missy. Her plot thread ran alongside the main story as The Doctor reminisced about the events leading to his guarding of the Vault which has been developing throughout the series. Whilst it came as no surprise who was in the Vault it could’ve been handled so much better. Firstly, whoever was in the Vault was clearly alive as we previously heard them banging on the door from the inside. Part of me was anticipating a Moffat-esque twist where it turned out not to be Missy inside. However with The Doctor venturing inside in an earlier episode and stating Missy directly by name that twist simply would not work. Again the more you think about it, the more you realise that it doesn’t quite work. Much like CERN.
CERN
The famous research centre’s inclusion was an intriguing prospect. Why a catholic priest felt the need to share a translation that the world we are in was in fact a simulation is beyond me. With that information why would they then feel the need to partake of a mass suicide, using stock from ACME it seems, again doesn’t make sense. Had those responsible at CERN believed that they had been the ones responsible for opening the portals into our world, unleashing the alien creatures, then that would’ve been more logical. It would also have generated a sense of guilt and despair. Instead they just couldn’t deal with the idea of being part of the simulation. Like most of the other pieces of this episode’s puzzle it simply could’ve been better.
