What is the worst thing you can say about a Shakespeare production? That it’s dull? That it’s overly reverential? That, if someone who had never seen Shakespeare before had to sit through it, they’d be put off the Bard for life? That it’s staged for wealthy white people living in detached houses in the Cotswolds? Well, we don’t need to decide, because you can say all of those things about Iqbal Khan’s Antony and Cleopatra, which is – and there’s no other expression for it – arse-numbingly boring.
