Oh, my god. This episode has sooo much to say about the way things are being run here on earth right now. The show is set some 20,000 years in the future, on some TV station. Things are being completely controlled by the top floor which no one is allowed to see or go to. The guy in charge is being controlled by a Jagrafess, some alien creature, that needs it ice cold or it'll die. It's controlling the human population by controlling what's on tv and what goes through the brains of the people broadcasting with implants that they need to do so to tap into the broadcast being fed by this creature.
The episode features Simon Pegg (Shawn of the Dead) as the 'Controller' who is in fact controlled by higher forces, ie, the Jagrafess.
I'll post more details later on about this episode. I just needed to get this off my mind, it's been bothering me for some time.
It makes it obvious to those that are awake that this is the type of thing that's currently happening with our media. I'm sure it may not be done in the EXACT way that it's happening in this episode, but it's happening none the less.
