kohlrak: It's actually not, and only the director thought so. The screen writer and original author wrote a utopian fantasy. If you'd like more info on the topic, i have a great video that goes into details, and suggests that the director probably only said as much as an excuse after the movie flopped at the box office, trying to suggest that maybe people didn't get the humor that wasn't really meant to be there.
Caesar.: Interesting. If the director changed the original screenwriter's vision, he succeeded. At least with me, that's the impression I got.
Judging from the comments section of the video i watched, he only made minor changes to accomplish this goal. Overall, the government is still a meritocracy, and service caters to disabilities, so no one's screwed just because they're disabled. Contrary to fascism, speech is not censored, but promoted (misinterpretation is understandable, given the focus on state sponsored messages), militarism is voluntary (you only loose the right to vote, which is tied to proving you don't have special interests by requiring service), government is regulated by a constitution, leaders admit mistakes, and the list goes on. Society is largely free, as evidenced by the pilgrims getting slaughtered by the bugs (they chose to ignore reason and became victims of evolution).
Have a good watch, because of this video i actually want to see Starship troopers, now. The government outlined seems absolutely fantastic.
