Query: Foundation's Fear is this Asimov fan's biggest fear!

One of the things that I have always enjoyed about the Foundation series is Mr. Asimov's easy writing style. Unfortunately, I found that reading Foundation's Fear was a laborious exercise. The author seems to struggle reconciling the scientific concepts initialized by Isaac Asimov with his own concepts of physics. The entire dialogue between Voltaire and Joan was particularly difficult to wade through, only to discover that this part of the story line had very little to do with the development of the rest of the book. I understand that some ideas had to be set up for the next two books, but I was frustrated by the sense that this book just didn't have a reason for being other than the commercial success guaranteed by the "Foundation" title. Given a choice between buying this book or rereading any of the original Foundation titles, this reviewer would recommend revisiting Mr. Asimov's authentic classics.
