This was an excellent movie! Think "12 Angry Men". I'm not used to seeing Park Hyung Sik as a timid person. He, and the rest of the cast members, did an excellent job. This movie is about a juror that takes being on a jury very seriously.
Even though everyone else initially just wants to quickly submit a verdict so that they can go home, Park Hyung Sik's character wants to ensure that justice prevails. They upon listening to his thoughts, the other jurors finally decide to take their job seriously and ensure that they bring back the correct verdict for the man on trial. This movie was full of suppositions, partial evidence and twists and turns. I got emotional watching this, I became so invested in the jurors and their quest for justice.
