Creator Backlash/Theatre

Examples of Creator Backlash in Theatre include:

Henrik Ibsen was not happy about having to change the ending of A Dolls House. The term he used was "barbaric atrocity". Ironically, due to changing values, the original ending is now perfectly acceptable. The redo is something of a Writer Cop Out. He also did not react well when feminists began lauding him for the play's support of their movement, which he denied.
A similar thing happened with Pygmalion, which higher ups wanted to change the ending so that Eliza and Higgins to get married in the end so it could have a standard happy ending rather than letting Eliza leave Higgins to marry Freddy. Needless to say, George Bernard Shaw would not be happy about the musical adaptation.
The Broadway flop 1600 Pennsylvania Avenue by Leonard Bernstein and Alan Jay Lerner was Bernstein's last and least successful musical; he was so ashamed of it that he didn't let it be recorded in his lifetime. As with Saint-Saëns and "Carnival of the Animals," one number escaped the ban: "Take Care of This House." Years after Bernstein's death, a concert version was issued titled A White House Cantata.
Love Life, a vaguely similar (and somewhat more successful) musical Alan Jay Lerner wrote with Kurt Weill, could not be revived in Lerner's lifetime because of his personal disdain for it.
Gilbert and Sullivan really came to resent their trademark comic operettas, claiming they would have liked to have been remembered for their serious works, too.
