From the rotten fish scene, I knew this one would be interesting.
The monsters are scary and yet your eyes fixed on the amazing details that they have done. They are even beautiful to watch in a way.
Korean drama has raised the bar again because this is not just a simple fighting and running away from monsters kind of movie but with lots of human elements which make the story much more meaningful and impactful (like Train to Busan).
There is not a second to be bored and you will finish it in a day.
