I got The Ark in Space SE and Revenge of the Cybermen the other day, so I finally have a full season of the classic series! (Yes, I'm a bit behind in my collecting.
So with that, I'm going to go through Season 12 in order. Just watched Robot. I love Tom's first couple of scenes (especially when he's jumping rope with Harry). The whole story is quite good, especially for Sarah, at least until the last 10 minutes. The giant robot really sent it into over-the-top silliness.
