While the idea of Korea and space exploration in reality may still be too far-fetched, South Korean filmmakers seem to be interested in exploring the search of mysterious planets above the sky. After we got the high-octane space adventure Space Sweepers on Netfllix earlier this year, the service recently gave us another outer-space show. The Silent Sea is a mystery thriller series that tackles the darker aspect of space missions and goes even further and deeper into conspiracy and mystery with its revelations and how this all connects to human civilisation's impending doom.
