The book, Starship Troopers, explores complex themes in original ways. The book is as much a critical look at democratic societies and in many ways challenges people to rise and maintain the level of behavior vital for a democracy to thrive. It does this by showing a previously democratic and open society that failed sometime in the past and morphed into one that coerced citizenship through various methods that were deliberately shocking to the reader.
It is a cultural examination of societal decay due to greed, immorality, apathy, and an inward turn toward satisfying the desires of the individual rather than meeting the needs of society. In that respect, the book is a probing challenge for people to remember that ultimate, John Kennedy was right when he said, "Ask not what your country can do for you, but what you can do for you country!"
Unfortunately, the movie merely touched upon these themes from the book and also showed a fight foolishly carried out. In the book, the bugs were fought in a vastly more intelligent manner vice the masses of people versus masses of bugs concept in the movie.
But, the movie did at least play on many of the book's valuable themes, enough so that it rose slightly above the cartoonish movie it would have otherwise been. I still think Paul Verhooven could have made a much better movie had he had the courage to resist the mass appeal aim and focused on the book's commentaries more.
