Well, we'll disagree on something, for once.
Here's a french proverb: « Le pire n'est jamais sûr. »
It's hard to translate in english but I think it comes from an inversion of Murphy's law, and it says:
« The worst case scenario is never certain. »
Excess of pessimism is not healthy, you know.
True, the worst case scenario is not certain. That's the importance of films like this: to warn of the dangers of a particular course, so that it doesn't happen. Which is why I said it was just as important to watch as 1984.
