Entertainment is more prolific, and it continues to maintain its place in defining a culture.
I grew up in a Korean household, but neither of my parents really watched Korean Dramas. However, in the Korean community, this source of entertainment is the most popular and cultivates the most money.
South Korea is known for its rapidly evolving technology and entertainment. As technology expedites processes and becomes more accessible, entertainment is refined and more particular.
Seoul is the capital of South Korea and a hub for entertainment and eclectic foods and activities.
Korean Dramas, or KDramas (as they are often referred to as), remain constant and similar in their story lines. The archetypes seem to be taken from the archetypes of a fairy tale. In this case, the Knight in Shining Armor is the wealthy Korean male who tends to be some heir to some large corporation. The damsel in distress is typically the female working two jobs while living in penury with her pitiful household. Their lifestyles could not be anymore different.
The Dragon, or the villain (depending on what fairy tale you grew up with), is typically the mother of the Korean male who does everything in her control to prevent her son from seeing the poor female. She tends to flaunt her money by dressing in designer clothes. She is a flippant woman that shows no respect to the female; she usually tends to offer the female money to stop seeing her son- a decision that determines whether she will choose to maintain her honor or lose it by accepting the money.
As the years go by, Kdramas remain popular and continue to thrive off of Korean viewers (majorly women) who fantasize of having their own "Knight in Shining Armor" come to rescue them.
What effect does this have on Korean culture?
Now I'm not saying to stop watching kdramas...
I'm saying that kdramas should be watched for what they are: entertainment. But as stated before, entertainment makes inroads and defines certain cultures, so do not let these dramas pervade you. Remember to watch these dramas with an awareness that they are just recycled fairy tales that should be watched with a light attitude.
