I love Nixon in China. I love the minimalist idiom which always enhances the action. I love the "I am the wife of Mao Tse-Tung" aria. I love the incomprehensible philosophy always lurking in the background. I could live entirely without the hand job in the last scene.
In fact the whole last scene is extremely anticlimactic. It was said several times that this is a modern masterpiece, and I am almost persuaded. The people being interviewed were pleased to be performing this opera on the day after the Revolution in Cairo. They made Mao and Chou seem to realize that revolution is only for a moment, like life generally.
