Spare a thought for the poor introverts among us. In a world of party animals and glad-handers they're the ones who stand by the punch bowl. In a world of mixers and pub crawls they prefer to stay home with a book. Everywhere around them cell phones ring and e-mails chime and they just want a little quiet.
I mean the first 'Back to the Future' is kind of a perfect script I think in terms of handling time travel the best. It depends on your definition. To me that means it effectively uses it in the story.
