What a great drama. The casting was perfect. All of the actors did a fantastic job. There was a lot of action, and the story allowed you to experience both sympathy and anger. Park Won Sang is lovable. The story really challenges your ideas about loyalty, and what's right versus wrong. There is nothing pretty about this drama. It is dirty and probably smelly. There is action until the very last moment. One thing to prepare for, at the end of this drama you will desperately want yourself a Mantis. You'll know what I mean after you've seen it. Buckle up and enjoy the ride. It's worth it.
