Well for one thing you laugh from beginning till the very end. Hadn't seen great quality movie in some time. That I really enjoyed and wasn't disappointed. The detective has great capabilities of discernment and is investigating serious stuff...you have so much fun as he is seeking the truth. Things are not what they seem. It is hilariously funny, witty, interesting,plenty action,his sidekick is great. It offers a little bit of everything, you don't get bored. Actor Kim Myung Min which I loved his role in King of Dramas and Beethoven Virus...has delivered an excellent performance. Kudos!
