The script was very subtle and managed to portray a multitude of motivations and justifications for more than one character. From what I could tell, it never said impressing a girl was the motivation for creating Facebook, and it portrayed Zuckerberg as someone who cared more about building stuff than he cared about relationships or money. Certainly it did make the (separate) implication that his handling of people/relationships/partnerships may be a source of regret as he matures as a person beyond 'I'm CEO, bitch.'
