Query: loved the idea, hated the execution

I really like the authors' premise of diving into the back story of OZ. However for me it just never seemed to come together. I often had the impression that the author had a momentary flash of inspiration that as he continued to develop just ran out of steam and eventually trailed off into pointlessness. In my mind this is especially evident in the last few pages when the author simply tries to wrap things up by simply writing charecters and events off as a complete mystery. As I say in the title... loved the idea, hated the execution.
