Saw this on Facebook, series arc resolved!

Incredible episode, just wow. As soon as it was announced where they were, instant goosebumps.

That was bloody incredible. Easily the best episode for quite a while. I knew it was coming because the fans can’t hold their water on socials but oh my I had goosebumps when the reveal happened. And the last five minutes when they got back to the airlocks… that was intense.

That’s how to do a sequel to such a beloved episode and although it didn’t give anything more major away about the entity it worked so brilliantly in a way that seeing the angels move in The Time of Angels, for example, didn’t while still showing that it had grown, learned and adapted since. Varada was once again such a star in the episode, even if I’m now starting to get suspicious like some others about just how much she does seem to know without asking 🧐

That's 2 10/10 episodes in a row and one 8/10 for me. Easily Easily by miles the best run in AGES

Agreed with everyone else so far that it was another great episode, I love how much of a contrast it was to last week also.

The way it built up the tension was done well and it managed to cleverly use one setting for a long period of the episode without it getting stale. They did exactly the right thing to keep the creature pretty mysterious as revealing what it looks like will ruin it. The only thing I think they could potentially have done was have them trying to manoeuvre through the station more once they realised what was happening, but it was still just fine as it was.

Definitely the strongest run of episodes for years would just be typical with the hiatus rumours lingering

These kinds of episodes tend to do best when we the audience know very little about the "monster" plus it's a sequel that works 🙌

Fantastic episode - need to give it a re-watch!

This series is shaping up to be so strong

Insanely good episode, possibly the best since World Enough and Time / The Doctor Falls? I'd heard the rumours about it being a Midnight sequel and my anticipation was high, though I was worried about whether it could live up to its predecessor. Honestly, I'm so impressed at how worthy a successor it is. It retained almost all of the mystery of the entity, whilst still breaking new ground, and leaving us with so many unanswered questions. I feel like so many different theories could make sense! More than one entity? Aliss actually being dead and the entity using her body? Shaya not even having the entity attached to her when she fell, or it transferring as she fell, meaning her sacrifice was in vain? I've not stopped thinking about it!

Rose Ayling-Ellis was sensational and I loved the commentary about how the other characters treated her and what they allowed her to hear, turning the subtitles off or even turning their backs (the Doctor included), sadly indicative of society I have no doubt. Belinda really shone too, I loved how sympathetic she was towards Aliss, and the way both Varada and Ncuti portrayed their fear of the entity was so good. Ncuti's facial expression when the Doctor was trying to communicate with the entity... superb acting, such a bleak, terrified expression.

This series is doing everything right so far. Despite being filmed right after season 1, it seems audience feedback has been taken into account, in post-production at least. I liked season 1 a lot but there's more breathing space here, the Doctor and Belinda's relationship already feels more layered than Ruby ever got, and I'm loving the TARDIS scenes to really ground the show and their characters. Intrigued about next week and how Ruby will slot back in, hoping the improvements can translate to her character too (though I know Millie always impresses with whatever she's given).

Finally an episode that delivers on all fronts and gives Gatwa a chance to show what he can do with strong writing.

A well crafted sequel to Midnight that neither takes anything away from it or over exposes the entity involved. And if you're going to rip off something - you might as well steal from Aliens, one of sci-fi's all time classics.

Only one minor quibble was the music in places, didn't quite feel right, specifically the flight (as in run away) sequence.

And even the tears felt earned this time.

A proper classic.

I can only imagine my enjoyment of this would've been enhanced had I not seen spoilers, but that's my bad, nonetheless, I think I'd comfortably put that up there with RTD1 era standard, I honestly thought I'd ever enjoy a Doctor Who episode as much as I did then.

I mean that was just sensational - a real sense of tension and dread, well-paced, well-rounded supporting characters that you actually felt for and didn't just feel like extras to be axed, an innovative casting choice that felt important to the plot and not just a diversity tokenism and why this creature is one of the best Nu-Who enemies - it truly stumps the Doctor, it's not clear what it is, wants or where it came from, yet it delights in making people become their worst selves through psychological torture just because it can and it makes it stronger every time. Even the Daleks don't feel as pure evil. They'll never recreate the original terror of Midnight, but they did a good job developing the creature's nature without losing the fear factor. The Mercury thing they used initially to get out of the room wasn't terribly well-explained, but that's the only qualm I can really find.

The great thing was (much like the original Midnight), it worked completely as a standalone episode so I'm hopeful it can go down as a classic (unlike 73 Yards which seemed excellent, but hinged on the series arc which turned out to be a total letdown which taints it in retrospect). I'd honestly question anyone that calls themselves a Doctor Who fan that found nothing to enjoy here, I cannot think of what else you could want.

This show really seems to have massively improved at the wrong time, I at least hope it keep this up for this season as the ratings were up this week which indicates there's good word of mouth.
