I have to say that "Golden Apple" is considered a flop ONLY because it didn't run. There is absolutely NOTHING flawed about it. As Ken Mandelbaum said about it in "Not Since Carrie", all the other shows in the book were in there because they failed the audience in one way or another and "Golden Apple" was in there because "the audience failed it."
I'm surprised that no one has mentioned "Lolita, My Love", yet.
