Only in the most vague way is this related to Train to Busan. This is a zombie movie based in South Korea set 4 years after the outbreak we saw in Train to Busan. I can admit that Seoul Station wasnt that good either, but at least they tried even with the choppy animation.

But here they go full ham on terrible, terrible CG and law-breaking physics. 4 years of disuse and the cars work, the roads are totally clear, there is electricity and functioning machinery. It just can't be.

This movie is clearly targeted towards fans of the original because there are some lines in English, awful awful cheesy dialogue that belittles the experience of living in a zombie infested wasteland and just contextually makes no sense at all.

And everyone in this movie is ugly and mentally insane. I liked Captain Seo, great character that makes sense, but Hwang is just bad to be bad. The military went full evil and now they're doing death matches. You also can't start a movie with heart wrenching scenes and expect us to care about the characters. Motivation for the main group also isn't really developed or explained and only really is justified by a flashback or singular line here and there.

All the English casting also makes no sense. I just can't understand why this film was made this way.

Large sections of the movies are completely in CG, they're actually awful and they look so bad. Skip this film, it just ain't worth it.
