This book is an approach to Christian ethics using theatrical improvisation as a lens by which to view them. As both a Christian and an improviser, this book was a natural for me to pick up. I have often told people that I think improv has much in common with faith, especially the mystical elements of the Christian tradition.
However this book is very mixed. I really wanted to like it - and much of it was quite good. If I were reviewing just the first half of it, I think I would be inclined to give it four or five stars. But the second half falters, and that portion I would not give more than two stars. Hence the mixed review.
Wells begins strong, building his case, chapter by chapter, for why improvisation makes sense as a model by which to explore Christian ethics. He discusses how theology is narrative and that narrative is drama and that improvisation is one of the most "true-to-life" forms of dramatic invention. He also explains why many of the other approaches to Christian ethics have been problematic, especially those that consider ethical dilemmas as equations to be solved using a pre-existing set of theological or philosophical tools. Wells thinks that such approaches will no longer work (if they ever did) in a pluralistic world. In narrative theology in general and in improvisation specifically, he sees a set of practices that are more in keeping with an "embodied" and "enacted" approach to Christian ethics. He encourages his readers to consider a form of virtue-based ethics, fostered by the church universal through spiritual habits and disciplines that have much in common with improvisation. He even examines a few common improv practices and ideas (e.g. status transfers, accepting offers, blocking, etc.) and applies them to Christian formation.
So far, so good. But in the last few chapters Wells tries to apply his approach to several current ethical questions facing the world, including cloning and genetically modified foods. I found his discussion of these topics abstruse and his application of improv principles a bit off the mark. As an improviser, I had already inferred how the "habits" Wells suggests forming might play out in situations presenting ethical dilemmas to create innovative "third way" solutions such as Jesus would have devised. My experience of these solutions in my own life (and my experience of improv performance for that matter) is that they are always unique to the situation. So the very act of trying to give a written example is a bit problematic. In some ways, I felt that Wells used ideas from improvisation to try to justify his own pre-existing answers to particular ethical questions. I don't know if that's fair, but that's how it felt to this reader.
SO, if you're interested in the topic of improv as a window on Christian ethics, read the first portion of this book. But you may want to avoid the latter portion, especially chapters 11 through 14.
