Don't expect too much from this movie. It is light on the plot and low on the thrills, but just exciting enough to keep you somewhat engaged. If you have seen your fair share of action movies, this one is just another movie to forget. 2PM's Junho is surprisingly one of the more entertaining aspects of this show. Honestly, we don't get much "acting" out of Jung Woo Sung, who is meant to be the main villain. By the end of the movie, we don't get much information about his character either, which is a pity. Clearly, Han Hyo Joo's character is meant to be the centerpiece of the show, but her character development is just barely there. Simon Yam has a cameo, as a wink to the original Hong Kong version of this story, Eye in the Sky. My verdict - meh.
