There are many things to enjoy in the Royal Opera’s revival of Donizetti’s Don Pasquale, but perhaps the most surprising is that the director plays it straight. This was my first encounter with Damiano Michieletto’s newish (2019) staging, and the plan was to approach it without preconceptions. (If we’re about to experience, say, a Bold Feminist Re-Imagining, I’d prefer to deduce it from the evidence on stage.)
