I'm not entirely sure what the theme of the video clip was, let alone the opening ceremony. None the less, it does have a point about the prevalence of religious imagery in everyday life, whether demons snatching souls, names like Cruella de Vil, or people singing about Jerusalem.
But saying "Whatever it is meant to convey, the message surely comes off creepy" isn't really a helpful analysis of anything. As for the New World Order, that was obviously a bust, as the old Eton world order still seems to be in power.
