Could "outdated settings" be the reason for the poor performance of KBS weekend dramas?

As the flagship dramas of a public broadcaster, the core mission should be to reflect modern family dynamics to evoke empathy and find hope within them.
The problem is that the settings in KBS weekend dramas fail to keep up with modern reality.
1. A daughter-in-law living with her parents-in-law
2. An eldest daughter sacrificing herself for her maternal family
3. An extended family living in an old detached house
4. Relatively outdated causes of family conflict
The 1950s generation, who are the core demographic for weekend dramas and are entering their senior years, is a generation that finds it difficult to empathize with such outdated settings.
Not to mention the 1960s generation...
Starting from those born in the 60s, they prefer watching Netflix over those kinds of dramas.
