For both amazon and amazonEditorial reviews I'm getting:
I have r3505 (2011-1-14) but can't see any calls to signing code in Review.php.
Maybe they have changed something again? The book-related Amazon API documentation seems to have vanished somewhere inside the AWS/Cloud documentation

Subject: RE: amazon reviews?
Amazon completely turned off their customer reviews API recently – you can now only get those reviews by embedding an iframe in your page. I updated the trunk to account for this a few weeks ago (see http://vufind.org/jira/browse/VUFIND-362). I think that editorial reviews still work, and the code should support the necessary signatures unless something else has recently changed.
