"Sea Fog" is one of those 'based on a true story' films that loses the thread the farther it deviates from the factual account of what was already a grim and riveting series of events. The final act descends into cliche thriller territory, but the first hour is an absolutely stellar portrayal of a group of hard-luck men forced into an increasingly dire situation by economic circumstances and their own moral failings.
Might be the preeminent example as to why the Chinese will never be able to win the war over populist cinema in Asia. The Koreans continue their entrenched, all-bets-are-off campaign to make the best mass-entertainment in the world. This is maybe the best peril at sea spectacle ever. A little bit of Steamboat Bill Jr., some of that Greengrass pirate-movie shtick, and, of course, specters of Ahab and William Bligh.
