Strong part of the movie; 1- Recording of action scene tecnique is good especially at first 10 min.(but i have to admit it i'm not an expert) 2- Story based on Lt. Choi and his character was made well. 3- Acting is good Weak part of the movie; 1- At first storytelling was slow. 2- They should explain a little more clearly about the issue of closing murder cases after 15 year and criminals won't get charged after that moment. Some important about the past of LT. Choi delayed intentionally in sequece of storytelling. i don't like it. it feels like they stuffed whole thing last 40 min. Anyway overall it is a good movie but i don't think people want to rewatch.
