This film is supremely stylish throughout. It informs the viewer about the reputation of the regime, the political pressures from the USA, the fear of attack from the North and the desire to replicate Japan without ever patronising the viewer of shoving it down your throat.
The lead performances, particularly that of the KCIA agents, are outstanding. The film exudes style in every shot, from the 'Blue House' as the quintessential VIP 'entertainment venue' to the military fatigues in the army HQ. The cars and suits demonstrate an appreciation of the kind of Hong Kong cinema Tarantino is so fond of plundering.
The film's triumph is to never let you sympathise or detest one character too much, that ambiguity allows for the stock of characters to rise and fall as their motives become at the same time clearer and more misguided.
Visually arresting with realistic and extreme violence the film is not for the faint hearted.
