Steven Berkoffs 'Greek' is Sophocles great tragedy of incest, patricide, plague and mutilation, re-imagined in Thatchers Britain, not in ancient Thebes. The language is poetic but filthy. The dialogue veers into unmentionable subjects. Characters swear, strip, have sex, humiliate each other and become suddenly and spectacularly violent. Not for the faint-hearted but a cathartic, visceral and moving piece of theatre. True to the shocking and intense drama of the original. Adults only.
