In a piece I found via Drudge on Village Voice, David Mamet describes Samuel Beckett's Waiting for Godot as "Twentieth century's greatest play." Huh? Say again?

Waiting for Godot is one of the low points of literature in the twentieth century in my estimation -- and it had to compete fairly hard to get that title! The only thing it accomplished was it served to help inspire the master playwright Tom Stoppard in his penning of Rosencrantz and Guildenstern are Dead. A Stoppard play certainly is far more worthy of the designation of the twentieth century's best (although I would probably pick Arcadia as the particular play of choice). I'd also submit Miller's Death of a Salesman and Pirandello's Six Characters in Search of an Author as worthy candidates.

But Waiting for Godot? No, that's merely a play where you are waiting for a plot.
