Admittedly bummed the villain is just a Dalek, but the worldbuilding here is interesting.

I marked out when K9 showed up. Totally 90s camp, and a blast to watch - those Troughton and Hartnell renders are egregious, though. Yikes!

The problem with the Sensorites is that it starts off really strong with the buildup to the reveal of what they look like and then it sputters a bit with the whole "don't trust the outsider conflict". Like the message about not believing xenophobia is great, but it could have ran along a little faster.

I find this one kind of interesting, partly because it puts Barbara on a really cool pedestal for the serial as a high priestess of the Aztec civilization and partly because it’s the first one I really feel like asks the question “can we as the Doctor and his companions change history?” in a way that isn't like with the Tribe of Gum.

The answer is, well… no. Which makes sense, but it’ll be neat to revisit this stance on the idea between this serial and the point where Donna Noble accidentally renames gravity to be “mavity.” I feel like this could have moved a little faster like The Keys of Marinus did, but for a four-part serial it’s alright.

I think it's a nice little environmental story. Fifteen is really written well here, like that feels like a good portrayal of the Doctor from the point of view of an outsider. I hope Inua Ellems writes more for the series beyond this and the upcoming episode. He has talent, and new talent helps keep the Whoniverse strong.

Really weird way to integrate the Bible mythos while sounding like a kid making it up as he goes, but okay!

for the love of god someone find Lilith already

No score on this because I wrote it. I'm sort of proud of it.

The mental image of Giles getting his ass beat is sending me. Cool and mysterious, huh?

A slow burn in only fifty-seven minutes seems silly. There's very little Auton action in this one, but makes for a great depiction of UNIT as an SCP-style task force.
