The plus side is, by letting it fall out of grace somewhat, is that it fosters new current works. With current standards.
We should not forget, that certain stuff in history can only be explained by the climate in society back then. The cultural works are an important part of this.
Think about the MASH discussions. Which war to pick, having mandatory ER time per episode etc pp. But again, some other stuff can only be understood cross generation if you know their culture.
