I really love this movie. I could say that this is REALLY my genre. Well, I also love actor Won Bin, that's why I watched this and so far, this is my favorite Korean Movie of all time. I like how the story flowed. Every single thing satisfied me. The action, the casts, the story, EVERY THING!!! Actually my favorite Korean movie is Daisy. But after watching this, it's my number one and Daisy got second place. This will really keep you watching it. This is WORTH watching, I'm telling you! :))
