If you expect the extreme logic and totally absorbing force of “The Big Swindle” from director Choi Dong-hoon’s new work “War of Flower” you will be disappointed. But the new film is still engaging enough to prove an intellectual talent rare in Korea’s Hollywood Chungmuro. A gripping combination of crime thriller and gambling movie, “War of Flower” released on Thursday pieces together into a complicated puzzle. The director’s taste for a brain teaser rather than melodrama is again evident in this gripping film, and viewers will be grateful for that.
