This series is just better and better. Tonight was brilliantly conceived, written and acted. Peter Capaldi is consistently outstanding as the Doctor. He will be so missed.

Loved it. This is the first episode of the current season that I thought was great.
It’ll be remembered of one of Capaldi’s Best!

A good story and character piece for our three protagonists, particularly the Doctor. However, I did feel that the threat felt a little to easily defeatable.

Fantastic episode, the first of the new series to be great on all fronts. Starting to wonder if the valeyard is the one in the vault?

I knew this was going to be a brilliant episode based on the premise and trailers and wow this episode proved me right! Incredibly creepy and has something Doctor Who needs more of; clever satire humour and really taps into fears of what Capitalism may evolve into; an unfeeling organisation valuing money over human life, making people buy Oxygen and forcing people to work after death. These things are clever and disturbing ideas that don’t sound totally impossible.

This has to be some of the darkest stuff Doctor Who has done! So brilliant plot, directing, Capaldi/12th Doctor were as always on top form,a great “Doctor pulls of a clever move to safe the day” and a really worrying ending that left me shocked!

I’m not sure what to say about this episode, as it’s confused my opinion.

For around 42 or 43 minutes, I enjoyed the setting, the grim sight of the suits murdering their occupants and then carrying their dead bodies around with them, the revelation that it was their bosses that were slaughtering them because they were underperforming and that they had to pay for the air they breathed.

In some ways, it reminded me of the Series 3 episode “42″ in. The spacestation setting, the zombie-like enemies in spacesuits, the countdown to disaster and the Doctor’s eyes being affected.

Once again, it was quite a political episode, but this time it spoke about an issue that affects all of us. It included references to the way workers are treated by bosses, how little they seem to be valued and are seen as replaceable and how AI will only make the devaluing of people worse.

I said at the start that the episode confused my opinion though and it did at the end. I agree with Dan in that the threat was too easily defeated. I was immersed in the drama of the episode and didn’t realise how quickly the episode was passing. I checked the timer expecting to see that I was 20 or 25 minutes in to find that I was 42 minutes in and the episode was close to finishing. The solution to the problem, whilst brilliant and logical as should be expected of The Doctor, slammed the brakes on the story and pretty much said “The End” and I was left thinking “Oh…OK, I was enjoying that”.

As such, I’m not sure what I think of the episode. It’s like I want to devide the episode into four parts and say that I liked Parts 1, 2 and 4, but I would have liked Part 3 to connect more smoothly to Part 4 to make the episode feel more satisfying.

Still, I thought the cliffhanger at the end that revealed that the Doctor was still blind was great. The Doctor has been disabled, which generates lots of story possibility for future episodes in terms of ability to defend the vault and have adventures with Bill without any ability to see. It was a great move.

It was a great story but had it failings. The main one was the ending. To suddenly jump from a room of people/zombies to the TARDIS was a little disappointing. The Doctor being blind, interesting!
However what I liked most and what a ;lot of people seem to have missed is the 2 obvious possible causes! The Space Station, when the Doctor and the others get into the suits, it reminded me of Ark In Space/Revenge of the Cybermen. Also, did no one else that the markings after death are very similar to the Cyberman poisoning in Revenge? Co_incidence?

This is the first episode of the current series which I actually enjoyed thoroughly. I was frightened, intrigued, and horrified in turns. Bill and Nardole just get better and better, while the Doctor, frankly, has reached the heights of perfection IMO. It’s also the only episode which set my mind thinking of future outcomes which, in my Whovian egoism, I’m fairly convinced I’ve worked out. Time will tell, but once again I now look forward to Saturday evenings with child-like anticipation.

A thoroughly enjoyable episode from a writer that had already penned the fabulous ‘Mummy On The Orient Express’ and ‘Flatline’!! Jamie Mathieson is fast becoming my favourite Who writer, he just seems to hit the right tone with his stories and the pacing is also spot on. Oxygen really is a wonderful Doctor Who story backed up with great cast performances. Really good stuff! :)

Well, what a fantastic though-provoking episode that was!! This series is just getting better and better with each episode, one happy whovian

As a yank, I’m genuinely impressed that BBC America aired this for our audience, given how relevant it is to how people are treated here in this day and age.

Hands down the best episode of this season.
