Tchaikovsky knew what he thought of the title character of his Eugene Onegin. ‘I loved Tatyana, and was furiously indignant with Onegin who seemed to me a cold, heartless fop,’ he wrote to a friend; and directors, by and large, have been happy to leave it at that. And why not? Dishy but emotionally unavailable Regency dandies have been a growth area in recent years — blame it on Colin Firth, if you like — and Eugene Onegin is probably the standard repertoire opera you’re least likely to see subjected to a directorial updating, in the UK at any rate.
