Somehow manages to out-stupid the Hollywood action franchises (Die Hard etc.) from which it derives.
Whilst you can nearly 100% certain that the all-American action hero will be alive and all the bad guys systematically dead at the conclusion of such bullet-fests, his Asian equivalent is just as likely to have earned himself an honourable grave.
The train-hijacking villain here is an impassive former government assassin with a knack for mowing down entire SWAT teams from a standing, uncovered position; a feat he achieves twice in this nonsensical Korean movie. It is offset by an apparent inability to put a bullet into the hero's girlfriend/stalker on several occasions when he has both motive and opportunity.
