Peter Ericson’s review published on Letterboxd :
The film begins as a mystery film in a military setting on the border between North Korea and South Korea, but it develops into a multilayered story that revolves around the friendship between a couple of soldiers from the two nations. Engaging, unpredictable, and unconventional, "J.S.A.: Joint Security Area" conveys a powerful message and features great cast performances. The final scene is excellent and very moving.
