I think this stories location as basically a season one story sitting at the beginning of season one means that it's often overlooked. After all, it comes before what might possibly one of the most iconic stories in the show's lengthy history. I think this story also gets a bad rep as silly, which it is. The kitty cat cliffhanger, the sink. Closing an episode with a man washing his hands is really not very dramatically compelling, I suppose. However, the story itself is fantastic. It has aged very, very well. This is Doctor Who being #woke in its earliest days, tackling cutting-edge scientific issues at the time like forever chemicals and even climate change. Humans impact on the world around us is front and center in this story and the two men who lead the life-size portion of this story both give gripping performances in a drama that is just as relevant now, if not more so, as it was in 1964.
