Tube ★★ Tyubeu 2003 (R)

After suffering a shocking personal loss, police detective Jay (Kim) finds himself relegated to the ranks of subway cop. He toils away until that fateful day when the goodguygonebad (Park) takes control of the train and terrorizes the community, giving Jay the chance to be a hero again and save the day. While the action in director Woonhak's Seoulbased debut zips along, the effort lacks that “certain something” (like a welldeveloped plot) that made its obvious inspirations—”Die Hard” and “Speed”smash hits. Korean, with English subtitles. 112m/C VHS, DVD .
