Marinus

Synopsis

The TARDIS arrives on the planet Marinus on an island of glass surrounded by a sea of acid. The travellers are forced by the elderly Arbitan to retrieve four of the five operating keys to a machine called the Conscience of Marinus - a machine capable of influencing all minds on the planet - of which he is the keeper. These have been hidden in different locations around the planet to prevent them falling into the hands of the evil Yartek and his Voord warriors, who plan to seize the machine and use its originally benevolent mind-influencing power for their own sinister purposes.

one of my favourite ever doctor who stories. it is very exciting, each episode has a different setting and plot so its very fast paced. similar to what key to time was doing but condensed into 1 serial instead of being spread over a season which makes it way better and more engaging. it shows how diverse one planet can be, which is something planets in scifi often lack, they are often all the same biome or culture everywhere. but in this you get the sense you're going to different countries. the episodes also have different genres. like snows of terror is drama, sentence of death is murder detective, screaming jungle is puzzles, velvet web is scifi. velvet web was probably my fvaourite for how barbara focused it was. i dont think season1 has too many character, because they all get enough time, but still it is nice to focus on just one of them and flesh them out more. its the first doctor lite stories as well. season 1 is pretty experimental in some cool ways


Ah, the fun variety show! While not as good as some tighter scripts, Keys of Marinus is a prime example of Terry Nation and his creativity at its best for me at least!

All the different worlds we visit are so much fun and while not every episode is a hitter, I appreciate the experiment quite a lot, definitely an underrated highlight of Season 1!

This one had its ups and downs; sort of inevitable when the premise involves hopping from one dangerous environ to another every episode of course, so let's take them one by one.

The Island: An intriguing premise, a mysterious landscape, interestingly deadly. Unfortunately Arbitan left me pretty cold. This machine mind-controls the whole planet into behaving according to its morals, and I'm meant to feel good about it? And based on what's happening around the planet, I really don't think it's done a very good job! The Voord have a fun design, but I have no idea what their deal is other than wanting the mind-control machine.

Morphoton: A really interesting concept for a dystopia, portrayed remarkably well for the '60s. The mind control stuff and the brain jars were really creepy, and I do love a bit of badass Barbara.

Screaming Jungle: Atmospheric, but doesn't cohere very well. The traps are kind of fun, I suppose, but the whole thing feels like a poorly-considered escape room. The ending with the attacking vines was great, though.

Icy Wastes: #VasorIsCancelled. All my homies hate Vasor, 0/10, worst villain of all time. A creep and a coward. What was I saying. Oh right the icy wastes. This was pretty good, some genuine moments of tension. Susan actually got to be badass for a bit, crawling over that icicle bridge.

Millennius: Courtroom dramas aren't really my thing, but the legal system of Millennius made me SO MAD I wanted to gnaw off my own leg (/pos). Really tense stuff, Ian was absolutely going through it on this one.

Island pt. 2: Still don't get what Yartek's deal is. What's he trying to do once he has the world mind control machine. Idk, this was fine, good villain defeat at the end.

Overall, I enjoyed this, but I kept feeling like they were trying to set up a point about justice and free will that never quite got made, and the Voord were WAY underused given that they were an attempt to recreate Dalekmania.

“Machines can make laws, but they cannot preserve justice”

C’est carrément du remplissage, et deux heures trente de “in ze boîte” ou “Mario bros” ne font manifestement pas une histoire. Mais allez savoir, j’ai quand même un petit faible pour The Keys of Marinus.

En fait sa plus grande force c’est aussi sa plus grande faiblesse. Il y a une variété dingue d’environnements aliens, d’histoires, ou de concepts, et chaque épisode redouble d’inventivité pour être différent. 

Mais là où c’est à double-tranchant, c’est que l'histoire à côté n'a pas vraiment de sens, et ne se contente surtout que de sa quête un peu vague. 

Bref, c’est fondamentalement pas terrible. Mais d’une certaine manière, ce Doctor Who n’a jamais été autant lui-même que quand Barbara a éclaté des escargots entre deux parties de Mario Bros ou Ace Attorney.  


It's like they put the Crystal Maze into Doctor Who. Go to a new themed zone, find the key, escape, and then repeat ad infinitum. Enjoyable enough, although I don't think the death scenes were supposed to be as funny as I found them

DOCTOR: I don’t believe that man was made to be controlled by machines. Machines can make laws, but they can not preserve justice. Only human beings can do that.

Episode One - The Sea Of Death

[TARDIS]

(The TARDIS lands on an island dominated by a huge pyramid. Ian is still wearing a silk Chinese jacket instead of his cardigan)

IAN: Any radiation, Doctor?
DOCTOR: No, nothing to speak of. The counter's hardly reading anything. Shall we take a look?
BARBARA: Pity you don't have colour television.
DOCTOR: Oh, but I have.
BARBARA: Where is it, then?
DOCTOR: Well, at the moment it's temporarily hors de combat.
