Considering this episodes reputation, I was actually really surprised about how much I liked this episode.
I'm a sucker for any kind of renegade Time Lord, and getting the Rani and the Master as a double deal just was a total pleasure to watch. The two of them - and especially the three of them, whenever the Doctor is there aswell - are just a really great combination.
The story itself was also more than fine. Nothing that was shockingly innovative, but the plot did it's job in functioning as a plot, and that's all I'm asking. At times it definetly dragged a little, but nothing that bothered me too badly.
Overall, probably my second favourite serial of the season!

I was surprised at how much I actually enjoyed this episode, since the rest of the season has been admittedly a little rough for me.
Peri and the Doctor finally feel like they don't want to jump at each other's throats like every five minutes (both literally and figuratively), which I admittedly really enjoyed. To be fair, I also thought Attack of the Cybermen was fine, but in this episode, I actually also liked the side cast and the world-building a lot, compared to the prior one.
At some points, the pacing felt a little off, but for the most part, I felt like the episode ran along smoothly and fit well together. The Doctor really got some nice Doctor-y moments, and Peri got some time to shine aswell.

I found myself unexpectedly enjoying this Episode. Usually, with the season one stuff, I find myself kind of indifferent, but their whole Journey through quite a range of different terrains was a joy.

I also thought the premise itself was rather interesting, and the longer season one goes on, the more I find myself really adoring Ian and Barbara. I like that Barbara is getting quite a few moments here. I like her a lot more here than I did in An Unearthly Child and Dalek!

This story was definitely my favourite one in the UNIT stranded series yet. It just carried such a weight and yet such a positive lightness at the same time. I love that this set gets the opportunity to get more time to explore its characters in such a personal way, and yet still feels entirely like a Doctor Who episode. It was also really something to see what becomes of the people that usually just stand on the sidelines.

I loved the Brigadeer and the interactions he got with the Doctor, and I adored the heartfelt moment the Doctor had with Helen in the end. It actually made me cry a little bit. I love that Stranded also tends to question the actual impact that the Doctor has on the people around him and if it's really a net positive. I know a lot of stories do that, but with this one, I just felt like it was handled in a way that is worth pointing out.

Overall, this piece was just everything I could've wished for.
