Admiral Yi Sun-shin (Choi Min-sik) was a revered Korean military commander, but after a Japanese plot involving false intelligence left him looking like a traitor he was relieved of duty and tortured by the men he had previously served and fought beside. The government’s attitude changes though when a second Japanese invasion heads towards their shores in 1597. The invaders sink most of the Korean navy and aim their forces for the capital, Joseon, leading a reluctant king to reinstate Yi as their last hope of fending off the enemy. He has his work cut out for him as only twelve ships remain in his ocean-going arsenal, a number that pales beside the 300+ Japanese vessels heading their way, but with the right strategy and the right location one man can fend off thousands. Well, that’s his working theory anyway. The Admiral — also known as the far more accurate and descriptive Roaring Currents outside of the U.S. — is a new South Korean film that tackles a legendary true tale from the Joseon Dynasty period, and it does so with historical detail and cinematic flair. In a way it splits those two attributes evenly into two halves of the film, and while both have their strengths they’re equally balanced by somewhat minor issues.
