Zero sum game implies winners and losers. If somebody wins, somebody gotta lose…. I don't agree with that. Because all boats can rise on a rising sea. Good films help other good films. Different psychology. If you're overly competitive, you say it is exclusionary, a zero sum game: I must win so he must lose. That's not true. We can all win without forcing the other guy to lose.
