Coughs and sneezes do indeed spread diseases in this amusingly feverish thriller, a Korean attempt to take back some of those lurgies let loose by Soderbergh's colder-blooded Contagion. A container full of immigrants unleashes a new mutation of bird flu on one of Seoul's ritzier suburbs, occasioning various disaster scenarios pitched around the level of a Channel 5 telemovie: the crisis boils down to whether Hunky Rescue Worker can help Plucky Single Mum to retrieve her Adorably Cute Daughter. Frequent spluttering montages provide silly fun, but this sort of doomsday projection surely ought to be terrifying.
