When the Korean and American governments announce that the military THAAD (Terminal High Altitude Area Defense) system is to be located in the rural county of Seongju, residents quickly become alarmed. As the local citizens begin researching the issue further they become increasingly politically aware, ultimately organising protests against THADD that continue to grow in strength and number. Blue Butterfly Effect (파란나비효과) documents the protests against THADD, from its grass-roots origins through to the nationwide coverage the issue generated.

The protests grow throughout the province
Director Park Moon-chil, who debuted with the wonderfully sensitive and empowering My Place (2013), returns with an inspiring tale of protest in Blue Butterfly Effect and in doing so cements his status as one of the best documentary filmmakers currently working in Korean cinema.
Blue Butterfly Effect proves to be so engaging largely due to the central subjects at the core of the story, as housewives, farmers, seamstresses et al from the community come together to explain how they became aware of THADD, detailing the passion and outrage it generated that ultimately led to forming a protest movement. Such scenes are brilliantly executed, providing not only an informative piece on the nature of the issue but also an insightful commentary on protest culture within contemporary Korea.
Director Park wisely goes beyond purely representing their opinions of THADD however, as he delves into the subjects’ voting habits, regional identity, and the increasing political and historical awareness each member experiences, unveiling acute character development. No matter how big the challenges over THADD become, the film never loses focus of the personal dimensions of the conflict, making the story an intimate portrait of nationwide debate and virtually demands audience investment.
In documenting the manner in which the THADD protests and responses escalate, director Park goes where few filmmakers dare to tread in depicting the ‘dirty tricks’ employed by those in favour of the military technology. In presenting the ways local politicians change stance and ‘spin’ alternative narratives, the collusion between the government and big business, as well as featuring elitist prejudice – misogynistic comments, and the head of the Education Ministry’s comment that 99% of Koreans are “like dogs and pigs” – combine to produce a startling portrait of modern politics, one that taps into the zeitgeist of anti-conservatism sweeping the country following President Moon Jae-in’s inauguration.

As politicians spin narratives, public outrage and peaceful protests increase
Verdict:
Blue Butterfly Effect is a powerful testament to the spirit of Korean people and the power of protest, as well as an important cultural text in its own right. Director Park Moon-chil again proves his talent as a documentarian to watch, for Blue Butterfly Effect is a film that, for current and future generations, and those interested in the politics of the peninsula, demands to be seen.
