It’s been two decades since Philip Ridley’s Ghost From A Perfect Place first debuted to a vastly divided critical reception at Hampstead theatre. Called “A masterpiece” in The Spectator and “Pornographic” in the Guardian, Ridley’s vicious and violently dark comedy depicting the gangs and families of a fictional East London caused a storm in the mid-nineties. The Arcola is now running the first revival of the play since its initial, fateful run, and is garnering a large and diverse audience (a much younger, more artfully bedraggled bunch than you might expect). On arrival, it’s difficult not to wonder if the ticket sales are due to the controversy surrounding play and author rather than any substance or quality. This is an undue worry. Here’s a list of reasons why you have to see this play.
