"The play has no plot, no climax, no denouement, no beginning, no middle, no end"--- elucidate this comment.
This play has been discussed in detail so a thorough answer is avaiable at http://www.enotes.com/waiting-for-godot. But the short answer is that, contrary to Aristotle's statement that "drama is the imitation of an action," Waiting for Godot is the imitation of non-action, a brilliant attempt at "effing the ineffable." Beckett was not interested in portraying psychological characters acting out a normative "dramatic" plot, but in conveying the pointless and purposeless fact of existence itself. To try to find normative dramatic elements ala Scribe or Aristotle or Freud is to miss the point of the work's creation. Having said that, however, the play is extremely entertaining and thought-provoking in production, using many elements from vaudeville and from dramatic dialogue. The final inaction of the play sinks into the audience viscerally.
