To be fair, you have to have a very high IQ to understand KOF. The humour is extremely subtle, and without a solid grasp of Japanese manga most of the jokes will go over a typical viewer's head. There's also Iori's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from Narodnaya Volya literature, for instance. The fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny--they say something deep about LIFE. As a consequence people who dislike KOF truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in Ryo's existential catchphrase "And don't forget it, Dweebenheimer!" which itself is a cryptic reference to Turgenev's
Russian epic Fathers and Sons. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Takashi Nishiyama's genius wit unfolds itself on their MVS cabinets. What fools.. how I pity them.
