UPDATE: December 30, 2014 - I was given a DMCA notice to take down the image. Interesting, there's a first for everything.
The Admiral: Roaring Currents (鳴梁/명량) was released here in the states last week. It was released in Korea about a month ago. The movie in only 4 short weeks, blasted the existing competition and distanced itself from The Host for the number Korean movie spot.
From the trailers, this movie looks good. Like way better than the ship battles of 300: Rise Of An Empire. I hope to catch it in the theatre but we'll see.
If you can, go watch it.
