Animator Yeon’s first feature-length live-action movie takes its sweet time establishing its core besieged characters - namely a workaholic divorced dad (Gong Yoo) and the neglected daughter (Kim Su-an) he’s taking to visit mom - before they board at Seoul for the trek to Busan, as hints of unrest and “workers’ strikes” percolate ominously on nearby screens.

It’s chew-chew on the choo-choo with “Train to Busan,” a Korean zombie flick from Yeon Sang-ho (“The King of Pigs”) that has more in common with high-speed disaster films and train thrillers than slow-walking undead sagas.
