The ugliness of that period in the 70s made that plastic baby factory even creepier. That looked like a horrible place to go to work.
Watching this again it's weird how casual the whole production is like everyone's doing just enough. Some of the sound can only be charitably described as "audible", like enough to make out what is being said. Just the most simple of blocking and delivery and what not. Did anyone run or even hurry in this whole story?
I liked Liz Shaw though and her coat with the white panels was kind of interesting. Her and the Doctor get on well enough but the whole thing is a bit too cozy. It seemed the later episodes had a bit more snap to them.
