It's an enjoyable movie. There is nothing wrong technically speaking...
Some things were kind of lazy; like how the police handled things and the rushed but weird editing and ending of the last 15 minutes of the film.
The acting is very great storywise not so much and you shouldn't expect a great bomb thriller story since I think this is a remake I've seen before years ago.
So what's wrong? At the end of the film certain editing choices doesn't make logical sense compared to the rest of this film. It feels like the director or the editor just wanted to finish the film due to a (personal) deadline or made a mistake during story boarding and not shooting scenes to connect it with the general flow and editing of the film.
As for the back story of the villain; uhmm...yeah? I guess where he is coming from but there doesn't seem to be any real justice and the film just made me feel I've been used as an old chewing gum.
Even though it is selling well/streaming well in South - Korea the general score it has gotten there by around 1 million viewers is around 5.3 as I write this, which in my opinion is an accurate representation if you look past the great acting, which is like a 9/10! If you are only interested cos you want to learn acting or just so you can talk about it cos all of your friends watched it; then sure watch this...otherwise? Mweh... Watch a different film if you can instead.
