I didn't think Andy Chakin was harsh enough with his review of this book. I'll comment about my opinion on Dragonfly. In general, I find it a fascinating read, but I don't really trust what I am reading.
Any book has errors in it.
But Dragonfly seems to push the errors envelope to new heights. On the FPSpace group I said a while ago that I heard a radio interview with Dragonfly author Bryan Burrough and from the tone of his comments I was appaled by the cloud of negativity he projected about anything he said. I really feel, that in spite of the book being skillfully crafted as an excellent read, that it really represents a negative agenda being pushed by the author. He seems out to bash NASA and its manned space program in any way he can. A case in point is Burrough's constant dredging up dirt on numerous individuals.
