The Daleks have been nicely spruced up for this story, with a new coat of silver paint.

However the jolly jaunty music when they first appear kind of undercuts their impact just a bit… #DoctorWho

Gotta love how they test their new machine gun attachment by shooting at a tiny model TARDIS. 😄

And what’s with that one Dalek who goes completely berserk and blows himself up because he lost his prisoner? Chill out pal. #DoctorWho

“Look out! The Exxilons had terrible taste in floor tiling!”

*CLIFFHANGER SCREAM!*

#DoctorWho

The Monster Of Peladon: I’m not sure the world was crying out for a sequel to The Curse Of Peladon but okay. 🤷🏻‍♂️

I suppose having some of the props and costumes in stock must have made it a cost-saving exercise. #DoctorWho

This is just a lot of running around in the same tunnel sets while the same extras playing guards and miners get killed again and again. #DoctorWho
Is Vega Nexos related to the Daemons? #DoctorWho

You’d think by now the Ice Warriors would have a to-do list for whenever they invade anywhere:

1) Find the nearest heating controls.

2) PUT A BLOODY GUARD ON THEM 24/7.

#DoctorWho

I like Terry Walsh’s cockney guard: “E’s in the frone room wiv the uvvers!”

There’s also the most hilariously obvious example of Walsh doubling for Pertwee in the fight scene in the cave, with his face clearly visible. 😄 #DoctorWho

Planet Of The Spiders: it’s a case of ‘Spot The Returning Actor’, since it’s like the entire guest cast of the Pertwee era have all returned to give him a farewell party as a send-off. #DoctorWho
Should Sarah be so friendly with and trusting of Mike? Given that it’s not been that long since he was quite happy for 99% of the human race to be wiped out and never have existed… 😬 #DoctorWho
Professor Clegg’s psychic powers are so incredibly strong you’d be forgiven for thinking that there’ll be a reveal of an alien having done something to him. But no, apparently humans having such abilities is a natural phenomenon in the #DoctorWho universe…
Episode 2’s chase sequence: okay Jon, you’ve had your fun driving and flying and, er… hoverboating, can we get back to the plot now please? #DoctorWho
Lupton must have the most banal reason ever for becoming a #DoctorWho villain. A salesman forced out of the company he worked for. How dare you! For that I will TAKE OVER THE WORLD!!

The first use of ‘regeneration’ to describe the change of a Time Lord’s body.

And also the first time that they try to build it up into a big moment and give the Doctor some significant final words. “A tear, Sarah Jane…?” 🥲 #DoctorWho

Robot: I don’t think anyone’s ever been so instantly fascinating, magical and appealing as the Doctor in their first episode as Tom Baker is here, in the scene where Harry tries to examine him and ends up jumping with him in the skipping rope… 😃 #DoctorWho

“You may have noticed Miss Smith, I’m a bit old-fashioned myself!”

“Nonsense Brigadier, you’re a swinger!”

Really Sarah Jane, I don’t think we needed to know that about the Brig’s private life. 😳 #DoctorWho

The Robot itself is a fantastic design but bloody hell you can see how it must have been a bastard for the poor actor inside to move around in. #DoctorWho
The guy they put on the reception desk of the SRS is such a swivel-eyed hateful Nazi. You’d think they’d find someone with a bit more charm and people skills to stop the organisation being “misrepresented” the way he says they’ve been. 😄 #DoctorWho

It’s really just the last ten minutes when the Robot becomes gigantic that lets it down, with the over-reliance on unconvincing CSO and tiny puppet-people.

Something that I’m sure influenced new producer Philip Hinchcliffe to try things a bit differently in future. #DoctorWho

The Ark In Space: now we’re talking. This is where the Fourth Doctor era really begins. You could just about imagine Robot with Pertwee, but this is pure Tom.

And the opening episode still works brilliantly, with no-one but the regular cast exploring for 25 minutes. #DoctorWho

Hinchcliffe’s production style immediately lifts everything. It all just feels tightened up, more focused. More effort made in getting everything absolutely right, or at least as good as it can be within the constraints of 70s production values. #DoctorWho
The soothing, hypnotic voice and music that plays when Sarah is being prepared for transfer into the cryogenic units is clearly influenced by the final moments of the euthanised people in Soylent Green. #DoctorWho
How would Vira (or whoever woke first) have got hold of the resuscitation kit and stimulated her own heart if it wasn’t for the chance presence of the Doctor and Harry? It was stored on the other side of the room! #DoctorWho
The Sontaran Experiment: probably not anyone’s favourite story of season 12, but it’s a decent enough two-parter to bridge the two tentpole classics either side of it. #DoctorWho
This is probably the best Sontaran mask ever. Having the whole bottom lip move (rather than just the middle bit) looks so much better. Something I don’t think even the modern series has managed. #DoctorWho
And speaking of the modern series, the Sontarans here are a world away from the more comical species they’re portrayed as nowadays. Sadistically torturing and maiming humans until the point of death. What laughs! #DoctorWho
Genesis Of The Daleks: well thankfully Terry Nation was prompted to write something different from his usual fare, and he delivered. You’d never think this was the same writer as some of the previous Dalek tales. Brilliantly bleak and grim in a ‘proto-Blakes-7’ way. #DoctorWho

Within the first few minutes the Doctor, Sarah and Harry have to avoid gunshots, land mines, bombs, poison gas… and have to rip gas masks off corpses to survive. No wonder Mary Whitehouse nearly had a fit.

Good! 😆 #DoctorWho

When the Doctor has to turn out his pockets, why does he have a pair of handcuffs…? 👀 #DoctorWho
The Nazi overtones are of course more blatant than ever here. And Davros is like something a kid would have feverishly imagined in a nightmare - “half-man, half-Dalek!”. I don’t think Michael Wisher’s version has ever been bettered. #DoctorWho

All praise to Peter Miles as Nyder too, what a fantastically evil bastard he is. Best henchman ever!

Though I’d love to know what he and the other few Davros loyalists were thinking at the end. Planning on living in a world with just them and Daleks and no one else? #DoctorWho

As Russell T Davies said years later - this was the first strike in the Time War…

Bloody Time Lords! #DoctorWho

Revenge Of The Cybermen: our first Cybermen story in years, but the production team seem to have forgotten the nature of the characters - with a highly emotive, irritable Cyberleader, strutting about with hands on hips making angry declarations. #DoctorWho
One unfortunate drawback of the Blu-Ray upgrade - the legions of dummies being used to represent dead bodies are now painfully obvious! #DoctorWho
The tedious infighting between the two Vogan factions is by far the dullest part of this story. We don’t care! Show us the Cybermen! #DoctorWho
This is the debut of the Cybermen’s allergy to gold. Just imagine, if in the 1980s they’d looked back at a different Cyberman story for inspiration it could now be a huge part of #DoctorWho lore that Cybermen are always defeated by nail varnish remover.
Nice of the Cyberman to have a conversation amongst themselves about vital plot information they already know, while Sarah Jane is hiding and eavesdropping. 😀 #DoctorWho
Terror Of The Zygons: this is one of the most atmospheric stories ever, complemented well by the spooky incidental music. Great reveal of a Zygon at the end of the first episode too, only flashed on screen for a second before the cliffhanger scream kicks in. #DoctorWho
The fleshy, organic design of both the Zygons and their spaceship interior is fantastic. Add to that the subdued red/green lighting and you get the most “alien” looking environment we’ve seen so far. #DoctorWho

The Brig gets a phone call from a female Prime Minister. Maybe we can use this to work out when the UNIT stories are…

Oh. On second thoughts, forget it. 😬 #DoctorWho

@gavinwinters Maybe it's Harriet Jones? Would certainly explain her looking tired.
