[Thor Joachim Haga]

I find Sakamotos gorgeous theme from Wuthering Heights expression this more or less throughout all of the movie.

Indeed, and these types of things are often tied to love themes. They don’t have to be, but they very often are. It has to be something more, though, than just a love theme. It has to be repeated almost incessantly, it has to have a certain obsessive intensity to it that moves it into ‘longing’ or ‘yearning’. Your WUTHERING HEIGHTS example is a good one, another one is “Across the Stars”, again from STAR WARS. The longing, the quest for connection (maybe across space and time), becomes kind of an entity in itself, that is about more than just love.
