Although Aussie director Simon Stone has staged only a handful of shows in the UK, it has to be said that you can see a pattern developing. Take a classic play - previously Lorca's - rewrite the whole thing into aggressively modern English that revolves around long, light hearted stretches of posh people swearing amusingly, season with a bit of Berlin-indebted stage trickery, and finally change tack and wallop us with the tragedy, right in the guts.
