Postmodernism in media rejects notions of absolute truth and reality. It blurs the lines between high and low culture and reality versus representations of reality. Postmodern media emphasizes style over substance and questions traditional narratives and interpretations. Some key aspects include a lack of originality, intertextuality between different media forms, and a collapsed distinction between media and lived experience where media simulations define reality. The Matrix film trilogy exemplifies these postmodern themes through its simulated reality and lack of clear distinctions.
