This feature length Animated Korean language film is a prequel to the live action Train to Busan and is very good. In addition to the thrills and chills of the infected feasting on the living, it delves deeply into topics like poverty, homelessness, exploitation, class, and the ease with which you can go from normal to expendable in the eyes of society. Definitely in the social justice tradition of Romero even if the Zombies aren't the same. 5/5.

My only complaint: 15 minutes in and I wasn't feeling the English language dub so I switched to Korean with English subtitles.
