Query: I was dissappointed.

I have read Asimov's earlier biography, I. ASMOV, and rather enjoyed that as a funny look into one of science fiction's most respected writers. This book trashes that down to a few measly pages, and ruins Asimov's clear, flowing style. After reading one book with this information already, I felt cheated.
