I am thinking that the review stars could definitely back fire in the world of Panda. For instance....someone clicks on a result because they assume there are actual reviews to be read. When they land on the page they instantly click the "back" button because there are no actual reviews.
Or they spend a long time looking for the non-existence review, in the course of which they read through the navigation and find something interesting to click through to.
