I really had fun watching this movie from start till the very end. Plot is not unique nor it has any unexpected twists but is actually delivers what should comedy action movie deliver. From one side ridiculous situations that main leads find themselves in, from other, quality fight scenes. (and they were actually reloading guns and not passing through 100 gangsters with 6 bullets as we see in most of the movies)
The most hilarious are the ways male lead finds solutions for the situations that this spy game got him into. And, generally, I really enjoyed the acting of Kim Young Kwang.
Overall I would really recommend watching this movies if you feel bored and want to laugh out loud.
