Reading 1- and 2-Star Reviews of Books

Well, as the title of this post suggests, I've been reading 1- and 2-Star reviews of novels - ones that I've actually read that are in the same genre I'm writing in.  I have to admit, they're pretty entertaining.  But other than that, I like reading them because they point out problems in other novels that I should make sure to overcome in my own.  I should keep these in mind, maybe even make a list of "What Not To Do When Writing a Novel."  Haha.
