What are the main tenets of New Criticism?

New Criticism. New Criticism was a formalist movement in literary theory that dominated American literary criticism in the middle decades of the 20th century. It emphasized close reading, particularly of poetry, to discover how a work of literature functioned as a self-contained, self-referential aesthetic object.
