Nihilism presented as animation. Both are by the same South Korean director & studio, and the themes explored are very similar. Sadly, the animation is limited to stiff (though expressive) low-budget CG.
In 'The King of Pigs', two former friends sinking in despair meet for the first time in 15 years and find themselves reminiscing over their middle school experiences. Typically violent Korean school culture (as depicted in fiction, at least!) gets injected with the struggles of trying to rise above a social hierarchy where the rich have free reign to intimidate and abuse those without money. One psycho child temporarily gives hope by fighting
against those oppressing others, with the two leads left watching on helplessly as the situation spirals out of control. Thoughtful emptiness is all it leaves you with.
'The Fake' is also about abuse of the poor, but from a different angle: RELIGION. A swindler has an unwilling priest deceive clueless rural folk and steal all of their money, while a horrible excuse for a human (a man that steals from and hits his daughter) happens to be the only person aware it's a scam... yet no-one believes him because of the sort of person he is. Violence and despair follow. Unlike with Pigs, it's hard to sympathise with anyone by the end of Fake, and the change of stance over religion at the end rams home the pointless emptiness of it all.
There's very little else like these two titles. Anime is WAY too mainstream for Japanese studios to allow such bleak, unhappy films to be made. There is a film called 'Tatsumi', which adapted numerous short stories from Yoshihiro Tatsumi (the GOD of adult-orientated manga and a master of nihilism) into an animated movie. Unfortunately, because it was done by a Singaporean studio, MAL won't add it to their database. But I STRONGLY suggest looking it up. It's far more anime than Korean CG films, at the very least. read more
