Query: Purtrid trashing of classcic

How did R&H allow their glorious stage work to be so trashed. The story structure is rearranged, ersatz and totally inapproriate to the moment comedy destroys what was a tense, moving and tragic denoument. On stage this was a boisterious, realistic portrayal of American troops in the Pacific in WW II, that stunned with its tragic-hopeful ending. Long, boring and one of the greatest of R&H scores is only a disheartening shadow of itself. A black filter should be permanently put over this atrocity
