Man, there’s nothing not to like about Terror of the Zygons. Sarah Jane (and Harry) as the companion. The Doctor in a tam o’shanter as he marches through the Highlands, The Brigadier in a kilt. The Doctor teaming up with UNIT to repel an alien invasion of Earth, which is my favorite kind of Doctor story. A cool alien race that would not appear again for decades, and would never been used as well again. And, of course, several appearances of Nessie. Man, that’s the stuff.
