Post structralism

Deconstruction, as applied in the criticism of literature, designates a theory and practice of reading which questions and claims to "subvert" or "undermine" the assumption that the system of language provides grounds that are adequate to establish the boundaries, the coherence or unity, and the determinate meanings of a literary text. Typically, a reconstructive reading sets out to show that conflicting forces within the text itself serve to dissipate the seeming definiteness of its structure and meanings into an indefinite array of incompatible and undecidable possibilities.

Example
"Shutter island"
In this movie hero play two characters so similarly afflicted
But we all know that it's just myth.
In which nothing is what it seems
