Basic plot is slightly deranged young man, kidnaps and tortures CEO of company convinced he is an alien out to destroy the planet. The plot keeps you in suspense the whole way through as you try to figure out whether he's mad or telling the truth. I saw this film on screen as part of Tartan Extreme Season, it contrary to the above review bombed badly at the Korean box office as it was to much for critics and audiences to take in. This film manages to be everything at once, comedy, torture, a thriller, a dash of sci fi, spoof of many films (usual suspects, 2001), commentary on low moral standards of modern life, the good old rogue eccentric cop/young colege hotshot cop routine and odd characters (the anti hero's girlfriend is a dumpy tightrope walker). At the core of the film is that old question, of humanity and whether overall there is any good in the human race. This is what makes the film great, it has an emotional core and central themes that holds, (just) all the disparate elements together and it really stays with you. The director handles all these elements skillfully and none of these elements detract from each other . To say much more would give the game away. The acting by leads and the supporting cast is superb and the film is has some wonderful set pieces, in particular with a swarm of bees. This film is the most frantic energetic film I've seen in a long while, its almost like he's scared he'll never make another film again so he has to get all the thoughts he ever had into this one. This film really is not for everyone, but if you're looking for something truly unique, crammed with ideas and energy and sets your brain cells in motion, then give this a try as words are thoroughly insufficient to describe it. I am pleased to see it has the fantastic critical response it deserves in the US(though some are still puzzled) so check them out if I haven't manage to convince you.
