I did not expect to have so much fun watching this movie. It was hilarious, even though the title made it seem like it was only going to be really serious and nerve wrecking. The twist and turns were really unexpected, and it was done so perfectly that i couldn't wait to see what would happen next. Each characters were played out well by the actors and you could see how the actors especially Jung jae young and Park shi-hoo took their lines and made it their own because there was truly some good acting to make me immerse myself into the storyline. The action scenes were truly fun to watch even though they overdid it at times. The last few scenes were mind blowing because it kept me wishing i was in that scene to beat the crap out of someone that truly deserved it. I recommend it because you might get something more out of it, and a really good laugh:)
