This movie reminds me of Parasite and the constant battle of the haves and have nots. It is easy to view this movie in its apocalyptic setting of a massive and devasting earthquake in a city as congested as Seoul, yet the true story here is the way people treat each other when any resource is at stake. It doesn't take a catastrophic disaster for that to happen--just everyday human greed and inhumanity. We see that now and we have seen it in the past and will see it in the future in every war and in every conflict, great and small.

The greatest disaster to ever befall mankind will always be ourselves. This movie will leave you thinking about it long after the credits roll and maybe change who you are. At least, I hope it will. We are all ordinary people though, so it probably won't.
