Explorers from an advanced, civilized culture travel to a dark, primitive outpost. There they find savage inhabitants, who they believe they can control. But soon the darkness turns on them, killing or corrupting those who dared confront it.

This narrative — which presents the people “over there” as some combination of monstrous, dangerous and seductive — is a staple of colonial storytelling. It's the general plot of Joseph Conrad's "Heart of Darkness," of "King Kong," and of the first installation of the "Rambo" franchise. It's also, somewhat unexpectedly, the basic storyline of Netflix's "Stranger Things," the second season of which was released on October 27.

"Stranger Things" isn't an adventure story; it's a hybrid of fantasy, science fiction and horror. As such, it isn't trying to glorify or critique or even talk about colonialism. It is certainly not trying to perpetuate colonial stereotypes. Nonetheless, the imperial subtext pops up periodically during the series, much like the second season's shadow creature pushes itself into our world. The fact that these stereotypes are so inadvertent simply proves how deeply embedded they are in U.S. storytelling.

In both of its seasons, "Stranger Things" centers around the danger created when military personnel at a base in Hawkins, Indiana open an inter-dimensional gate into a dark, twilit shadow realm called the Upside Down. The sole inhabitant of the Upside Down, in the first season, is a humanoid monster dubbed the Demogorgon who feeds on flesh. It is animalistic, violent, and hungry. The Demogorgon, in short, could be a frightening “native” in a Tarzan serial.

The colonial parallels are accentuated in the second season, in which the Upside Down turns out to have additional inhabitants and more consciousness. It begins to reach into the real world with a series of quickly growing, thick, vine-like tendrils.

Jungles have long been used to evoke uncivilized, creeping barbarism, whether in Africa in the late 19th century or in Southeast Asia in the mid-20th. In "Stranger Things," the military makes short expeditions into the Upside Down to burn back the untamed foliage — a detail that seems especially telling given the series' occasional references to Vietnam. The Cold War itself becomes an excuse for invading and controlling the Upside Down, just as it has historically been used as an excuse for invading and controlling other nations. In the television series, scientists worry that if word of the Upside Down gets out, the Russians will try to use it as a weapon.

Another staple of colonial narratives is the reverse invasion; the terrifying fear that someone will do to us what we did to them. The most famous example is "The War of the Worlds," in which H.G. Wells directly compares the Martians invading Britain to the British invasion of Tasmania. "The Tasmanians," H.G. Wells wrote, "were entirely swept out of existence in a war of extermination waged by European immigrants, in the space if fifty years. Are we such apostles of mercy as to complain if the Martians warred in the same spirit?”
