The country that brought us Samsung and LG, Korea has been absolutely killing it when it comes to technological advances and modernization. The latest talk in the film industry is the 2014 Korean production Roaring Currents, whose trailer is below:

Directed by Kim Han-min, whose short films won many accolades in Film Festivals around the world, is getting much international attention because of this, his latest film on the 1597 Battle of Myeongnyang, which saw an important Korean naval victory against Japanese invaders.
It’s the kind of story with universal appeal, a David vs Goliath tale of Korea’s paltry 12 ships defeating Japan’s 330 ships. However, many of the film’s detractors are calling it anti-Japanese, with online commenters going so far as to call it Korean propaganda.
An understandable assumption; tensions between Korea and Japan are at an all-time high, centering mostly on the issue of comfort women- something which, ironically, Korea itself is fighting among its locals, with news of a group of US comfort women filing a lawsuit against the South Korean government for forcing them into sexual slavery for the American military based in Korea.
Roaring Currents reportedly had the highest weekend receipt in South Korean cinema history:

In the five days since it hit screens, it has earned around 36.8 billion won, according to the Korean Film Council’s official tally. On both Saturday and Sunday, more than one million paying customers went to watch the movie, the first time that level was broken. (Source: Wall Street Journal)

Actor Choi Min-sik won Actor of the Year at the Asia Star Awards as well as Best Actor at the Buil Film Awards this year. The film had its US opening last August.
