This movie shows the dregs of society. There are gangsters, organ harvesting, drugs, child abuse and violence. If you are a person that is easily shocked, then you might want to skip this movie. I loved it. Tae Sik is a character that is afraid to love. His character has many deep layers of emotion and Won Bin portrays them all very well. The little girl Kim Sae Ron who plays So Mi is perfect. I hope that she keeps it up and I get to see her in many more dramas in the future. The bad guys do a great job too. I really hated them. The actions scenes are awesome. If you like action packed movies with a touching plot, then this is definitely a movie that you should watch.
