Violence, bad language, blasphemy and a bit of nudity. If that offends you, it’s even more reason why you must see this play. Philip Ridley is probably the most exciting playwright in Britain today and even if this is not his greatest play, it’s a very good example of his work. It starts with the tense domesticity of The Fastest Clock in the Universe and ends in a surreal vision more akin to Mercury Fur. One of the more extreme characters even suggests that we are seeing the end of the old world and the beginning of their new one. Despite its in your face, violent presentation, there is so much subtlety and ambiguity that any description is impossible: just go and see it and ask yourself why doesn’t the National Theatre have the courage to commission him?
