Query: Good history, little else

Dan was my first serious teacher 18 years ago. I have moved on from him to better masters, but I appreciate what he did for me, and I respect his intent, but this book fails as so many tai chi books does, because it's a series of useless photos. How do you get from one posture to the next? The essence of taoism is change, and these postures are static. Even if it was a video, it's pointless. You need a teacher to hit you! He should have written a book just on the history, because that is the strongest part of the book.
