While writing a script somebody might have asked- so what genre would be good? Drama, thriller, romance, comedy, fantasy element, slice of life, etc., and the producers were like- YES.
The makers have utilised every possible thing to make the show appealing. The concept is not new and we have seen many dramas with this plotline. What drives the show is its thriller part, at least for me. The story has many loopholes and there are many questionable coincidence that happens out of blue and some scenes look over exaggerated and they look really silly but the actors are the reason that you would forgive it all. The comedy part is not bad but the law cases are not intriguing enough and I find myself skipping those scenes most of the time. All the actors are superb and it's been a while since I last saw Jin Hyuk in a show plus all the veterans in here are really good. Overall it is a decent watch that one might see if there is nothing in particular interesting to watch.
