Just bear in mind that two-thirds of the people here rated it above average or outstanding.
Yes. That's very telling, isn't it?
Not really, no. Look through the history of those threads, you'll find that there's a certain subset of people here that think EVERY Star Trek book is outstanding, and their definition of 'poor' is voting above average.
Not just in the Lit forum, happens in most of the tv/movie threads as well. Everything's awesome or sucks, not much room for something just being ok...
Given how review threads usually go in here, the general tone and comments in this thread are a pretty good indication that it was not as well received as some of the previous books. Can draw your own conclusions about the worth of the voting buttons from there, but if you consider that most threads only draw a few negative votes, 1/3rd negative still means something by that standard...
