Cush Jumbo's soliloquies are deep and thoughtful, every word heard as they should be.  This is the third time I recall the Young Vic choosing an excellent Hamlet but giving him a problematic production.  There was Peter Brook's curtailing Adrian Lester's Hamlet to just Hamlet's lines in the play.  There was Ian Rickson's setting of Martin Sheen as Hamlet in a psychiatric ward with Gertrude as a fellow patient and Claudius as the consultant psychiatrist.  We walked through an installation of the back of a hospital with a dispensary before seeing the play.  The last really successful, all round Hamlet I remember at the Young Vic was Paul Rhys's 1930s European royalty in 1999.
