14’s theme was “What’s Your Breaking Point” with the asylum aesthetics.
And yes, pre-2000 had themes. Eyegor, “Primal Scream,” etc.
And that’s part of the confusion for a lot of fans. People view the “theme” as this tightly integrated narrative when it’s not, really. It’s the tag line and the “look.”
What was the “theme” of the Caretaker’s or Director’s years? It wasn’t the characters. The themes were “Your Time Has Come,” and “You Ought to Be In Pictures.”
Basically, the “theme” is a combination of the tag line and the primary aesthetic.
