It was interesting but also really boring at the same time. I don't know why I expected more from this movie.
The acting in this movie was very good but it couldn't have been otherwise. Lee Byung Hun, Gang Dong Woo, Kim Woo Bin, Uhm Ji Won and Kim Jin Kyung are known for their good acting. The first half of the movie was quite engaging, but after that it started to drag on, it got boring and I kept finding myself distracted from watching. The ending was just predictable. The movie definitely could have been shorter to be a little better.
