Another show which I have seen recently, and one which I would quite recommend seeing, is Why I Don't Hate White People. The production is currently touring the country, and if you do decide to go, try and attend a performance followed by a q&a session, for Lemn Sissay is fascinating, informed, articulate, and funny - it was by far the most insightful post show talk I have attended to date.
The piece itself is a thoughtful exploration of white British attitudes to racism and features a very engaging and charismatic performance from its writer, Lemn Sissay MBE. It is, I believe, well written, and fairly well constructed, and is delivered from inside an all white set inspired by Sissay's 2008 Cape Farewell expedition to the North Pole. My main criticism would be of the physical enactment of the many poetic metaphors which I felt detracted from their meaning and encouraged only a literal reading - it is however still worth seeing if you get the opportunity.
