Note that all this works for Kantians too. The point is: what artists to spook their audiences, philosophers live amongst. Also: setting your film in a dream excuses most sins (plot incontinence, blunt catalepsis, hysteron-proteron, narrative-time/discourse-time looseness).
"Inception is proof that people are not stupid, that modern cinema is not trash, and that it is possible for blockbusters and art to be the same thing."
