Samuel Beckett's 'Waiting for Godot' is a cornerstone of existential drama. It meticulously examines the inherent limitations of language in conveying human experience, the construction of identity through discourse, and the profound existential angst associated with the human search for meaning and redemption in an indifferent, often absurd universe. These thematic layers collectively define the play's enduring significance in modern literature.

Postmodern theater frequently challenges the existence of objective, universal truths, reflecting a fragmented and skeptical worldview. Instead of providing clear moral lessons or definitive answers, these plays often employ ambiguity, meta-theatricality, and non-linear structures. This approach forces the audience to actively engage with the performance, questioning the nature of reality and constructing their own interpretations, thereby emphasizing the subjective nature of meaning in a complex, post-structuralist world.

Postmodern drama is defined by its rejection of traditional, rigid structures and its embrace of fragmentation, irony, and intertextuality. While postmodernism is diverse, it generally avoids the 'well-made play' structure characterized by strict adherence to a script. A minimalist stage and rigid script adherence are more aligned with traditional or modernist realism rather than the experimental, self-reflexive nature of postmodern performance.
