Well... the film is not great asides all of the fighting scenes (the one in the bus is excellent). Not terrible though. Plot really did not serve this film at all. 7/10.
These scenes alone are enough to bring my butt to the theater (whennnnnn they will be open in my country), they are from a recent promotional clip so not spoiler but I will put them in spoiler tag just in case
It's funny to read this topic and the Korea box office topic as a Vietnamese whose country suffered immensely under the Japanese rule and later the Korean attack.
