Asura: City of Madness

Whether he made this hard crime film with comic undertones as criticism of the corruption scandals that ravaged South Korea in recent years, only Kim Sungsoo knows. He was undoubtedly inspired by them. The backdrop is the fictional city of Annam, where detective Han Dokyung sorts out the dirty business caused by the thoroughly corrupt Mayor. Possibly to pay for the care of his terminally sick wife; possibly because he is himself rotten to the core. Han is very busy. The Mayor will stop at nothing to rake in profits from a huge real estate project. There are lots of bodies. Han gets noticed by Internal Affairs as he seems to be involved in the death of a colleague and the disappearance of a prosecution witness. 
Endless darkness filled with bullets, knives, axes and people who lose it for no reason; our guide a misanthrope who has to uphold the law, but who would prefer to blow up the whole city.
