This is the most suspenseful, intense movie that I have watched. It is August 2021, and I finally got around to watching this movie, five years after the release. The K-movie production staff, crew and cast outdid themselves. All of Korea must have worked as extras. The last seven minutes had me tearing up.

The acting by the main cast was very good, and the Zombie extras must have had a lot of fun playing the ghouls. Sadly, only two of the train passengers survived. The director is a visionary, bringing the screenwriter's mental thoughts on paper to virtual life.

The virus that began in a lab seems to have an eerie message of a deadly virus that is unleashed on mankind.

It is a rollercoaster train ride from the time, the first zombie appears at the train station.
