I know the name David Mamet, and am even familiar with some of those stories you mentioned, but I have yet to read this book. And it sounds exactly like the sort of thing I like to read.
I found your discussion on the 3 acts in writing interesting. I recently read a blurb in a book discussing why it is actually 4 and not 3, and i came away with the same conclusion - the author didn't get it. Sure split the 2nd act in two and name it 4 acts. Big deal, nothing has changed. The fundamental arc of the story still exists as it always did. But I didn't realise - until reading your post - that there are others out there with that view.
Thanks for the introduction to this book. I will look out for it.
Thanks for your thoughtful comment. There's no accident I've reviewed this book first. It really has helped me along with a deeper understanding of dramatisation.
