What’s the point of Star Trek Discovery?
People tell stories for a reason. Typically stories provide for the audience escapism, educational lessons, validation of culture, and a sense of social or moral control. These can all manifest in different ways, but generally speaking, those four functions are at the heart of any story worth telling.
More simply: the stories that resonate over time and place mean something to their audience. They tell us about our world around us, about our communities, about ourselves.
