You know the kind of movies where the government has gone bonkers mad and turned the place into a virtual prison..
The Running Man
Brave New World
Logan's Run et al.
I find them amusing and whenever I watch I like ot make up my own back stories to this and I can't help but think the people "let it happen" let their world become like that.
Of course these stories exist to entertain and not run for 3 hour epics to fill our need for information on their worlds to satisfy the viewer. But I just like to sit back, enjooy the film, and go "ha ha" at the general population in them while cheering for the hero..
And why are these kind of movies popular? Is it that the heros are just common "everyman" type of people?
People like good storytelling.
Good storytelling requires a protagonist who faces a challenge.
Protagonist with no challenge = no story.
Challenge with no protagonist to face it = no story.
A dystopian society -- whether it's played dead-serious (1984) or played for laughs (Brazil) or a combination of both (Escape From New York) -- poses a great challenge.
Not all protagonists in dystopian stories are everymen. Escape From New York's Snake Plisskin was a former Special Forces legend. Will Smith's character in I Am Legend was a high-ranking figure with training to deal with the plague that wiped out the world. In those stories, an everyman would be grossly inadequate to the task.
One everyman protagonist who does come to mind is from Golden Age SF: Isherwood Smith from Earth Abides. His everyman status played a direct role in the story, in that he had no special talents to deal with the almost-complete wiping out of the human species. He was left to restore humankind (and back to the then-present  level of civilization) with nothing but resourcefulness, powers of persuasion, and hope.
I never viewed Blade Runner as a dystopia.... I think more a fractured world. As people were free to come and go as they wanted. They bought and sold replicants to do dirty, grungy work, and I'm pretty sure some other stuff that humans would loathe like the Darryl Hannah character who was manufactured as a living sex doll.
I viewed the replicants as unwilling particiapants bordering on slaves.

And "V" was just one man who manages to galvanise everyone to rebel against the government. The ending of this movie was great. People power. My point with these fictions is we never really know why or how the population view their world. Did it just happen or did no one bother to protest?
Take 1984 for example. How and why did this happen, and did the people realise what was happening?
