Query: Still in Shock!

I saw the Boston Lyric Opera production of this opera on Jan.30th, 2000 and don't quite know what to make of it. Yes, the music at times was compelling and dramatic but the opera as a whole left me with a feeling of shock and disbelief. To go from the previous work done in boston "Aieda" to this, is taking a quantum leap, one whose journey I don't think I want to take again.
