This is an entertaining show but to me, rather UNDERwritten. Some more historical background would help. The history of anti-semitism is long and deep in Austria and to simply show the anti-semitic mayor Lueger for a moment and not explain the extensive background even a little leaves the viewer uninformed. Remember:Hitler was an Austrian, not a German, and there is a lot more to say. It would not detract from the story, just make it more meaningful.
