One of the things I like about this movie is the comedy doesn't interfere with the action. It's not slap-stick humor either. Also, a few of the action scenes are bloody, whether it's knife-play or gun-play. I'm surprised South Korea produced such a movie in the action-comedy genre, but it's a welcome surprise. Just as typical action-comedy films from South Korea, the two leads are bad-asses. But, it gets hinted at from the very beginning, so it's not like it's thrown into the audiences face unrealistically, half-way or even toward the end, like Extreme Job did.
