Tudor and Stuart London

I think that the author of this text is insane. Of course you cannot 100% accurately reconstruct a performance at The Globe the exact way Shakespeare did it. It is impossible to do this and I think that the author is too harsh about it. If they did not have these modern convienences, very few audience members would attend. Also, it's confusing if you are not from England and reading this. Sometimes the author uses British slang that I do not understand and that loses me for a while.
The author uses numbers attached at the ends of sentences that need further explanation, but I cannot find where these statements are explained. The author has such odd transitions, too, between topics; he switches so often that I find it difficult to follow along or become involved. I understand that he wanted to keep the book short, but I feel like he tried to cram too much into one tiny book.
