Yes, exactly this. (Although sadly, nowadays you have to qualify the lightning flash of “Star Wars” with “I mean Ep IV, 1977” .)
That is why stories exist, for that lightning flash.
Now, sometimes there is a moment near the end of a book or film that seems to distill the whole story down to its essence, and you feel in that moment like you can see and understand the whole thing super clearly. And you CAN – but only because you’ve experienced the story up to that point.
I’m pretty sure those distilling moments are related to the Crucial Element, at least most of the time. I’m going to pick on @Lakis 's novel August in the Vanishing City for an example:
He grabs her, covering her hand with his own, and pulls her toward him. And for a moment, the thin, uncrossable line separating them is breached.
That’s the last line of the book, and gave me chills because in some ineffable way it really does capture the whole story, all the throughlines. The Crucial Element of Ability is really strong here, connecting the RS, MC, and OS throughlines directly, with some help from the IC. Amazing since @Lakis wrote it before he knew about Dramatica!
Anyway, that’s what I’m talking about. In those moments – as author or reader/audience – you feel like you could describe the central inequity and every aspect of the story in a few words. But if you try, you never have the language – the best you can do is convince someone else that “it’s really amazing because of X and Y and Z” and get them to read it.
(As an aside I think it’s a good lesson to think about your Crucial Element toward the end of your draft – that’s when you’ll have the best understanding of what it means in your story – and let that come out someplace important.)
