Guys, T:SERIALS applies, which reads in part: "...it's perfectly fine to cite a single episode rather than the whole serial..."

Personally, I prefer it because it's more precise. It's not necessary, strictly speaking. But it's certainly allowable. And you probably shouldn't change the citation from something which is more precise, like "An Unearthly Child", to something which is less precise, like An Unearthly Child.
