The celebrity culture is infantilizing us. We are being trained not to think. It is not about the disappearance of film critics. We are the canaries. It is about the death of an intelligent and curious, readership, interested in significant things and able to think critically. It is about the failure of our educational system. It is not about dumbing-down.
I’ll just add that one thing which makes me to turn off a tv documentary is when I realise that all it contains is statements (“soundbites”) without arguments. I turn off lots of tv documentaries these days – or rather: I don’t turn on the tv to watch them.
