According to a researcher at the University of Vienna, popularity of Korean dramas have their foundation in Confucian values they transmit, which Asian viewers can easily identify with. Respect for elders, filial piety, family-orientedness, and the display of perceived "Asian moral values" play an important role in Korean series. YA Entertainment, the American distributor of Korean dramas, believes that part of the attractiveness of these series come from the quality of camera work, scenic locations, and spectacular costumes, which make the "final product very stylish and attractive, with arguably some of the highest TV production values in the world." Korean series follow their own formula, are innovative and don't conform to Western television productions. Stephan Lee from "Entertainment Weekly" called Korean dramas "fascinating and weirdly comforting".
