This play has a lot going for it. 3 stars might even seem a little harsh, considering the quality of the writing. But the truth is, it's a little too didactic. The action a little too drawn out. What is a wonderful idea for a social critique play, that murdering a homeless person can magically renovate a room in a house, which is really just a speeding up of the real process, did not constitute 115 pages / over 2 hours of drama. Philip Ridley is a great writer, but this is not one of his greatest plays.
Having said that, I'd still watch it.
