My vote for the most “anthropological” pop culture phenomenon goes to Star Trek. They collect biological, historical, political and cultural data on each society. And they even have a running debate between scientific empiricism (Spock) and humanistic interventionism (McCoy). While the “prime directive” prohibits interference with the “primitive” societies they encounter on other planets, they never seem to actually abide by this rule. Especially Kirk, who seems keen to write an interplanetary update to the Sexual Life of Savages.
