I'll add my support for this, in general, since there are so many dissenters:
Norvig doesn't do anything to address ones that think the book is poorly written or gives bad advice (for modern times) or confusing in style, for instance, just claims the 1-stars aren't looking for the same information as the 5-stars.
This amounts to "the book is perfect. your review tells us who you are." which is an extremely-limited-use stance when it comes to critiquing, and simply insulting to anyone who wants what it's offering but doesn't like the presentation.
