I saw this at the Melbourne International Film Festival in 2011 and have been dying to finally get this on blu-ray. This is a movie that has very few guns but all the knives and meat cleavers you could ask for. And uses them all.
The violence is brutal, bloody and often up close. It is also excessive and never ending. Western films often glorify an intense moment of violence whilst The Yellow Sea follows it to its (un)natural conclusion. Remember the days when Seagal would walk into a room with a knife and kill everybody? This is the modern equivalent but done with Asian flair, outstanding production values, and a human-centred, relevant and modern tale. Like many Asian films, it's also slightly confusing if your mind switches to autopilot. So whilst you could watch this as a straight 'action' film and be happy with the violence, it's much better getting involved in the story too.
The perfect non-Western action film.
