This film was everything I expected from it. A typical and predictable Korean cop comedy with the action accumulated at the end of the movie.

The actors had great chemistry. The plot was ordinary. A duo where one person is just themselves and the other pretends to be friendly and trusts them when they act undercover. Enemies who ultimately befriend and cooperate with each other and at the end save each other.
In the North Korean scene, I cried a little.

It was fun and enjoyable enough not to feel like you wasted your time.
