I think I know how you feel. I read a few reviews and people in LA going off on each other in comments section. Having had the "pleasure" of sitting through several premiers of new operas, I understand the sense of disappointment in hearing a work that doesn't work.
The irony though may be that Wagner may have had a hand in turning Opera into this. His culminating achievement of evolving Romanticism into gesamtkunstwerk, the total work of art, may have killed the traditional arias. Everything - a note, a word, even silence - must add to the total drama of the opera. Given the modern atonal and serial bent, you end up getting an opera with no signature moment or musical themes.
