Officer Black Belt Review –
Today, we are looking at a fascinating film that, for all its strengths, never quite came together. Conceptionally, you have an interesting story, the scenario is solid, your leading man is charismatic, and you are exploring an essential area in society. However, even with that strong foundation, what happens when you don’t land the tone? Well, that is what we will explore today.
So, to set the scene, Lee Jung-do (Kim Woo-Bin), who loves the competition that comes with sporting achievement, will try every martial art, race to deliver food orders, even dabble in some esports, anything he can find ‘fun’. He works so hard at this that he has multiple black belts across numerous disciplines. When Jung-do saves a police officer from being attacked by a former prisoner, he is propositioned by Kim Sun-Min (Kim Sung-Kyun) in the Seoul Probation Office to become a Martial Arts Officer to help monitor released felons and intervene if they re-offend. It is a job where you sit around, not doing much, interspersed with high action.
