To be fair, you have to have a very high IQ to understand Portal. The humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. There's also GLADOS nihilistic outlook, which is deftly woven into her characterisation- her 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 Portal truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in GLADOS existential catchphrase "then there will be cake" 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 Kim Swift's genius wit unfolds itself on their screens. What fools.. how I pity them.
And yes, by the way, i DO have a Companion Cube tattoo. And no, you cannot see it. It's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 IQ points of my own (preferably lower) beforehand. Nothin personnel kid
