This is not going to be a very thorough review; rather, I just wanted to add my two cents. The main point of critcism many people seem to have towards this book is the fact that its characters are shallow and hardly ever develop. While I agree with that, I believe that that's the point; Isaac Asimov's psychohistory deals not with individuals; rather, it concerns itself with people in general and thus I think if the book focussed too much on developing individual characters it would not quite fit in with the theme.
