Well, that one's tough because it depends on how you look at it. It kind of illustrates the issue I'm having separating this fourth subgenre from the others: is he running from his heart's desire, or is he afraid of commitment? It straddles a fine line.
That's right. He's basically afraid of everything. From girls to clowns, everything just seems to be there to frighten him, so he creates these rules to try and deal with it.
The second defines something like Brokeback Mountain, which again felt very close to a Heart's Desire (he wants Jake Gyllenhaal) but it didn't feel quite right, given his kind of resistance to it.
I'd also say that the first could define Four Weddings slightly better than my above attempt -- to quote the Dramatica analysis: "Charles is driven by emotions that he cannot fully understand."
That's a very well-reasoned theory, @Greg. I think you might have found the fourth. I'll give it a little thought, but I think you have it there.
The outright fears stuff, I think, would be an inverse of the heart's desire perhaps -- avoiding their inner fears.
