MusicMan - I never said Titanic or Parade were classics. I merely offered them as examples of shows from the past that have yet to be performed when the author of the article says "there is little left from the past to do", he is non-specifically referring to not only classics to be revived, but also ignoring shows that have yet to have a West End production at all. Regardless your opinion of them, they have gone on to critically acclaimed productions and have proven to have a life beyond Broadway.
"But somewhere along the line, its creators succumbed to the self-conscious, postmodern cliche that plagues so much of twentieth century art: only ambivalence, cynicism, despair, irony, emotional aridity, textual/musical difficulty, inaccessibility, grotesqueries, etc. have meaning or validity, thus robbing the musical of its joy, poetry, pathos, romance, humor and VARIETY."
Simply because you don't like a show, doesn't mean it has no joy, poetry, pathos, romance, humor and variety, almost all of which was in Caroline, or Change and Parade to name a couple. You want the art form to fit into a neat little box and stay there for eternity, but art evolves through social, political, scientific and technological change and musical theatre is an art form that will evolve as well.
"...the newer shows placed a greater value on the overintellectualized idea and the writers' own 'self-expression' at the expense of audience identification and enjoyment."
The same could be said of Sondheim, which would explain why nearly all of his shows were not commercially successful.
"Is it any wonder that audiences have blithely sought their pleasures in confections such as CRAZY FOR YOU, MAMMA MIA, THE PRODUCERS or the DISNEY shows, while the serious musical has, at least temporarily, reached a dead end?"
It hasn't. That is your opinion talking, not fact. The Producers, though I don't care for it, is a perfect example of entertainment and ideas. So is Hairspray, Aida, Rent, Wicked and The Frogs. They are simply not the entertainment and ideas you personally desire. But then, few musicals could ever live up to the lofty standards you set for them, which is why you will be continually disappointed.
It's minds like yours that rejected rock and roll as a form of music and remained firmly glued to Lawrence Welk as the world continued to progress around them.
Audiences choose the confections because as history has shown, audiences has always chosen the confections. Successful "serious musicals" (as you call them) have ALWAYS been an exception. This is not a new development.
