A fast-action thriller set in the near future. Excellent performances by the principal actors helped by an excellent script and cinematography. In real life, the lead actor is a former South Korean Army soldier, and the lead actress is the daughter of a senior South Korean military officer. This possibly helped them give strong performances in a military-esque type of drama. And they are both tall; quite tall for Asian actors. I'm not sure if tall Asian actors are now being pushed in thrillers because they will come across better to international audiences or not. But these two certainly have potential for international success.
The only reason I gave this movie a 9 rather than a 10 is because there is a contrivance at the end. Spoiler Alert!!! The noble leader of the renegade group of law enforcement reformers is obviously quite insightful and intelligent. So why would he want to kill off the heroine at the end, knowing she had to do what she did to save her very physically-ill younger brother? This was obviously done to set up a big, impressively-choreographed fight between the group leader and the hero over the heroine's fate. Everything worked out in the end, but I thought the writer could have done a better job of finishing the story without making the group leader have a temporary mental lapse near the end.
This movie, like the outstanding "Train To Busan," shows that Hollywood better pay close attention to South Korean film makers, especially pertaining to thrillers.
