This tendency could perhaps be read as an allegorical commentary on the planned obsolescence of our own technologies. A common element in postmodern architecture, for example, is the sticking together of different styles from different periods in the very same building or even room. The term often used to describe this splicing together of different styles and genres is pastiche . Perhaps this is one of the reasons that we are given so many images of eyes in the film. As Rachel Saalwaechter suggested, we have the sense that identity itself is being formed by popular culture.
Reality is supplanted instead with what postmodernists tend to term the simulacrum .
Deckard in Bladerunner is clearly a morally ambiguous character.
