CHARACTER

The degree of optical distortion of reality to the viewer also relates to the uncanny valley by producing a visual effect that is believable, despite its abstraction. Animated films (Tezuka's Metropolis, Scanner Darkly, etc.) produce a distorted visual that so obvious to the viewer that it makes the characters more believable:

"... when you look at a photo or realistic drawing of a face, you see it as the face of another. But when you enter the world of the cartoon - you see yourself... the cartoon is a vacuum into which our identity and awareness are pulled... an empty shell that we inhabit which enables us to travel in another realm. We don't just observe the cartoon, we become it!"
