Having watched the entire video from start to finish, I can't imagine what is so particularly controversial about this production that would warrant such fervent booing on opening night (edited out of this video unfortunately). Just that its not dripping in sequins, crystals and faux marble pillars. Sets are pared down and drama directed at inner conflict rather than outward theatrics. Direction was certainly unconventional but is done within and with respect to the text and characters. The three lead cast members' singing was excellent, particularly Diana Damrau of course. No subtitles unfortunately.
