I wanted to like the film because I'm a fan of Sung Dong Il from 'Dad where are you going' and Lee Kwang Soo from 'Runningman' but the movie is an absolute mess. The pacing is slow moving from one scene to the next without a sense of flow or establishing a sense of time. The story line is simplistic with the dialogue being very unnatural even for veteran actors to save this movie. What's worse in each scene is the terrible angle cuts of the close ups of the actors and wide establishing shot. There is just a lack of direction in cinematography and the cuts are absolutely chaotic that it's not even pleasant to watch visually.

My advice is to watch a different movie.

This movie is funny and hilarious. The case is not too complicated but you will be surprised. The three main actors act naturally and the chemistry between them is good. One of the best Korean movies I have ever watched.
