Discuss the contribution Shakespeare's The Tragedy of Hamlet makes  to Rosencrantz and Guildenstern are Dead, beyond the obvious lending of characters and the intersections of the dramas, particularly at Elsinore. Are there themes and motifs in Shakespeare's play that make it especially appropriate as a partner and resource to a twentieth-century drama? What are they? Is Rosencrantz and Guildenstern are Dead a "tragedy" in the same way that we consider Hamlet a tragedy? Do Rosencrantz and Guildenstern end "unhappily" or "unluckily"?
