First Time Feeling: Hits him hard, not least because, at the time, he's found and is listening to an old vinyl album of Beethoven's Ninth Symphony, one of the most tremendously moving pieces of music ever produced by the human species. Even the script describes this introduction to human emotion as 'unfair'. (But it does a lot to explain his subsequent actions.)
Showy Invincible Hero: The director finds it boring when the villain "gets a few good licks in" on the hero because he has no intention of subverting audience expectations with a Bad Guy Wins ending, and thus, there's no point in making it seem like the villain has an advantage at all when the result is a foregone conclusion. He does acknowledge that not everyone likes this approach. And yet, for all Preston's physical invincibility, he turns out to be incredibly emotionally vulnerable.
