In this case, go ahead and believe the hype. Yeon Sang-ho’s nervy South Korean zombies-on-a-train epic is getting rave reviews, and deservedly so. Not only is Train To Busan a tightly wound horror movie, it’s also a tense disaster film in the spectacle tradition of Irwin Allen.

First and foremost, Train is an expertly paced thriller that darts deftly between hysteria-inducing sequences of undead mobs running amok, and scenes of quiet love and devotion between a father (Gong Yoo) and his daughter (Kim Su-an) that actually succeed in developing their characters to the point where we can root for them in good conscience.

Harried, overworked fund manager Seok-woo must escort his demanding daughter on a train trip to visit her mother and his estranged wife. As so often happens, real life gets in the way of even the best-laid plans, as a nearby chemical leak causes average citizens to turn hungry, fast, and ferocious. The featured zombies have a rubbery acrobatic grace as they gamely snap back to life after succumbing to lethal bites.

All too quickly the train is overrun with bloodthirsty berserkers, and the supporting players emerge from the chaos. There’s a tough guy and his pregnant wife; a high school baseball team; a sociopathic tycoon, and a pair of spinster sisters. Alliances form and crumble, and as we learned in Romero’s original, a house divided cannot stand. As usual, the rich guy can’t be trusted.

Nonetheless, these characters routinely sacrifice themselves for the good of the remaining survivors, continually casting humanity in a noble light. Seok-woo begins the story as an ineffectual office drone, but through attrition and necessity, evolves believably into a hero to save his child.

Director Yeon Sang-ho displays uncanny action-film finesse at times, contrasting the closed-room claustrophobia of the train interior with sweeping panoramic views of an embattled choo-choo chugging down the tracks to its final destination. Train To Busan is indeed a grim ride to survival, but it’s a satisfying one. And the scenery is magnificent.
