I am giving this 4 stars because of the technical excellence of the singers and the production itself. There are some very good in depth reviews already and I would encourage you to read them as they give a knowledgeable insight into the opera.
My only comment is that this opera is not for me. I prefer opera's like La Boheme, La Travista and Carmen, this opera is like a long string of sung recitatives with only a couple of traditional arias. This is only my opinion and I would not want to put anyone off trying it.
