I saw the movie and never read the book. I made the dumb assumption that at least the movie would follow the same spirit of the book. However, the director, Paul Verhoeven, shares your contempt for the book so much that he basically satirizes the book. He couldn't even finish reading the book.
I found the movie excellent and decided to read up the
wiki page on the book because of the various views I've heard/read about the topic.
I can understand the rationale behind the theme of the book, "... to demonstrate that social responsibility requires individual sacrifice." I can even understand people that would want to require some sort of civil service from citizens. But I'm wary of government enough to offset any advantages I think society gains from such requirements. And to add such service to gain suffrage is even more scary.
In any government, people can oppress others. But at least in a democracy, I know I'll at least have a vote. People can change the democracy to where they have more power and not all democracies are equal. But as we limit that democracy, how do I know that I'm not the one being oppressed? How do I know that stupid people won't devise the test that results in stupid officials and stupid policies? And the smart people get castigated and labeled fools?
