Science fiction provides a window into the social and cultural dilemmas that characters have to tackle, like what is the culture of the alien species, or if robots have feelings.

Movies like I am Legend, or 2012 explore the controversial topics of today like industrialization, biological warfare, the environmental crisis and cyber-terrorism, pushing them into a future fantasy world that can examine the problem closely.

Hostile aliens rocked the world when the book The War Of The Worlds was adapted as a radio play.

Aliens, hostile or friendly, have always been the surest, most profitable route to success, as verified by pulp stories that were bought in American magazines in the last seven decades.

Science fiction often predicts the future, with most popular stories almost always having elements of fixing a society on the verge of decline, or which is already in a state of dystopia.

It is ultimately a positive genre, a portal in which we can see where our world may be headed, drawing from contemporary life, breakthroughs in medical and space science, technology and even history.
