Postmodernist films are characterized by self-conscious use of styles and conventions, mixing of styles and media, and distrust of theories. They challenge mainstream narratives and aim to destroy audience suspension of disbelief. Key conventions include pastiche, flattened emotion, hyperreality, time bending, and altered states. Pulp Fiction and Run Lola Run are examples that blend genres, have nonlinear narratives, and reference other works. However, some philosophers criticize postmodernism as meaningless and unable to add analytical knowledge.
