Haewon (2018)

According to a survey by the U.S. military government in 1946, 78% of the South Korean people wanted socialism and only 14% capitalism. By appointing the pro-Japanese collaborators and the rightists, Rhee Syngman, who had not received the people's support, massacred those groups and civilians that were political stumbling blocks. In dealing with the Jeju 4.3 uprising in 1947 and the Yeosun incident in 1948 and The Korean War having broken out, massive civilian massacre became regularized.

Unfortunately the movie Haewon is not yet available on HBO Max.
