Amit Chaudhuri on why he believes modern movies have a "spiritual glumness".
"Digitisation's subterranean agenda", he says, "is to repress natural light."
Unlike old black and white films which were flooded in natural light, he sees the light of digitisation as a grey light.
"We're meant to be distracted by drama, violence and special effects; but, crucially, enchantment is withheld from us."
