Opera is not the same as a museum piece, people usually go to listen to the music, or a particular singer, not necessarily to see the acting out of a story ( which you usually know anyway) I am assuming the director kept the music the same? The production of various operas does change, and personally changing the dramatisation would not stop me going to see a particular production. I have seen operas set in vastly different settings from the original, and enjoyed them. I’m looking forward to seeing Carmen at Covent Garden next month, I’ve seen it before and love the music, so I’m interested to see what this production is like. I saw Rigoletto recently and was rather surprised by all the nudity, which I dare say wasn’t in the original production, but really enjoyed the performances, ( the Duke still didn’t get his comeuppance though, which would have been a feminist ending!)
