I treat reviews for books like I treat restaurant reviews. When they complain, what are they complaining about? Like if they say "beautiful language but took forever to build to any sort of action" I'm alllll over it. Or if they complain that it was super weird or that the ending was too ambiguous or something I might check it out.

I also occasionally amuse myself by reading one and two star reviews for classics. Like the kids who complain about everyone having too many names in War and Peace. :)
