Query: A very good comprehensive portrait of Tony Kushner

Actually I would rate this item a bit higher. Perhaps 4.5 stars? It's very well done, full of important information, detailed, and, the most important aspect, intelligent. I am also very happy because that's what I really wanted and needed, that's the thing that I expected when I ordered it. And I'm definitely not disappointed. A real comprehensive portrait indeed. Proper for scholars, drama and theater lovers, well, everybody, who's interested in Tony Kushner's works.
