The Edinburgh Festival is huge. Enormous. Gigantic. So it’s a big success right? Maybe not, writes David Benedict. “We’re talking art, not merchandise, so why are we so hung up on size? Shouldn’t we be vaunting quality over quantity? Not at Edinburgh. Less is no longer more. This is the festival most easily mistaken for a marathon, and every year some schmuck attempts to beat the record for the number of events crammed into 24 hours.”
