I agree with the previous reviewer. Some more details:
Gennaro, Lucrezia's hidden son, is very young, young enough to hop about while talking to Lucrezia, the beautiful lady he admires... in other words he is a restless innocent 14-year old. But the role is played by Pavol Breslik, a fully grown man probably in his late thirties or early forties, as can be seen when he takes off his white shirt to wipe the blood from his scraped knee (being motherless, Gennaro cannot be expected to have a clean handkerchief in his pocket). Result: he looks like an idiot!
Lucrezia has red hair, most of the time. Toward the end of the opera, she suddenly appears in a long-haired white wig; she removes it during the scene (her red hair remains in place), then puts it back, for no apparent reason. I assume there is a deep psychological or philosophical meaning to it... But no footnotes to explain.
At Princess Negroni's party, we see a girl sitting on a chair, staring in front of her. She doesn't move; she doesn't sing. She just sits.
The staging is DO IT YOURSELF! If a character is supposed to sit at a table, the singer appears carrying his own table, with a lesser character carrying the chair!
WARNING: The booklet informs you that the same director, Christof Loy, is responsible for the staging of Roberto Devereux, also with Edita Gruberova. That is another one I shall avoid, sight unseen! I would also avoid her Norma: there is no way a 65-year old woman can pretend to be the mother of "due pargoletti", two children under 10. CDs are one thing, but DVDs and Blu-Ray discs should strive to look believable! "Suspension of disbelief" applies to the plot, not to pretending that grandmothers have babies!
