The Host
Bong Joon-ho's 2006 mutant monster adventure fantasy broke box office records in his native South Korea and is primed for an inevitable U.S. remake. Just deal with the subtitles already and see the original on a screen worthy of the large-scale mayhem of Bong's gross-out creature feature!
Bio-terror and mass hysteria ensue when the U.S. military orders the dumping of toxic chemicals into Seoul's Han River, from whose depths emerges a "mutant carnivore-cum-somersaulting slimeball [that] can swim like a fish, scuttle like an insect and run like a Spielberg raptor" (to quote J. Hoberman's entertaining Village Voice review).
When it kidnaps an adorable school girl, things get personal.
