Well, I typed 9 pages of quotes to use for research from it, so I obviously thought it was really useful. It's different in the fact that it relies solely on McNiff's experiences, but he is established enough to do that. I found his chapters and reflections thoughtful and useful. I wasn't as much of a fan of the coaching tone because I'm using it more from a practitioner standpoint, but he did a good job being encouraging to what I imagine is his intended audience of people less familiar with Expressive Arts.
