This movie is your traditional thriller, so if you're looking for Mission Impossible or something similar, look elsewhere. This is a movie primarily about the conditions which led to the leader of the KCIA nearing the end of former Korean president Park Jung Hee, Kim Kyu Pyung, to assassinate his former friend. It is a movie about Kim and his relationship with the former dictator president, and ultimately, about how that friendship rapidly deteriorated over the events leading into Kim's decision to launch his short-lived coup. As such, while action is present and is of a high quality, it occurs very rarely. As someone whose interest in Korean history has only recently emerged, I can't comment on the exact details of this movie, but from what little I do know of it, the movie appears to be grounded in reality. I particularly appreciate the attention given to Kim's apparently more benevolent nature than his colleagues, a driving force in the leadup to the movie's climax. As someone concerned with politics, I appreciate the simplicity with which complex arrangements are described - no extraneous information is given to the audience, and the movie allows any lesson on moral or political philosophy to be inferred by the audience rather than attempting to spoon-feed it. One of those lessons is very clear: dictators grow rotten with power, and whatever moral ambitions they may have used to excuse their actions in taking power fall sickeningly flat when applied wholesale to keep themselves in power after they've become the very thing they fought against.
