I have been disappointed by some of the more recent Korean films that promise to lead the audience into deep dark psychological realms but deliver only rather trite and confusing plots even if the cinematography and acting were stunning.
After being almost overwhelmed towards the conclusion of this animation, I believe that the spirit of Korean cinematic honesty, confrontation, complex psychegeography lives on in works like King of Pigs.
I won't go into the story - the plot is straightforward enough: bullying, high school hell, the sickness of a society based on hierarchy and class, corruption of the system...but the delivery of the narrative gets under your skin in completely original, unexpected ways.
The end twist is utter believable, and delivers a double whammy, so stay glued to your seat.
I can't understand some of the low ratings, though many might find this very difficult to watch due to the horrors depicted. It wasn't an easy film to sit through, but it is worth every effort to do so.
