[null and void]

It seems to me, however, that someone arbitrarily put the brakes on all negative reviews at some point because the vast majority of recent ones are all 5 star.

Makes sense. Why would Amazon do anything to discourage people from buying a book from them????

I realize that. I try to suggest an alternate book for every negative review that I post for just that reason. In the case of the review I posted above, I deleted the line where I recommended another book because I didn't want that to become the focus of this thread and I didn't think it was relevant.
