Science Fiction portrays two possible visions of the future usually, utopian, where everything is perfect, and dystopian, pretty much hell on earth. In this symptom we are exploring dystopian science fiction and what makes it great. Dystopian sci-fi generally can deliver the more powerful messages, because usually the events discussed have occurred, although to a lesser degree. It tends to be more relatable to the average viewer or reader because being the flawed creatures we are, we have real life examples of nightmare societies and oppressive powers to compare it to. Utopia's though, just don't exist.
So here is symptom 30, we talk a lot about Demolition Man, have a great side bar conversation about Aliens and discuss Planet of the Apes, all excellent examples of a flawed, dystopian future.
