The Help by Kathryn Stockett

I did enjoy reading this book but I don't think it was a great piece of literature. I don't want to be snobby about it, but it did seem a bit cliche and predictable. And the characters thinly drawn...at least some of them. But I enjoyed reading it, so I feel bad be critical. After all, shouldn't reading be pleasurable?
But really....did all of the white women have to be so evil? Except for Skeeter, of course, the author of the book that is being written within this book. The Help tells the story of black women working for white women in Jackson, Mississippi. They are surrogate mothers to the white women's children, cooks, cleaners, servers, and more. But they can't use the family bathroom, have their children share schools, or the lunch counter with anyone who is white. One of the white women, Skeeter, an aspiring writer, decides to be brave and tell the story, anonymously, of the women who have been so crucial in the upbringings of all of these white women, but who live a very separate and not equal life. Apparently, Kathryn Stockett, the author, felt compelled to tell this story after moving to New York and feeling conflicted about her prior life in the south. So, the book seems semi-autobiographical.
Now, on to the problem I had......
I am sure that there were (are) plenty of women like Miss Hilly, one of the worst white offenders in the book, but she was painted in such a negative way; you wanted her to get lynched. And really, is the point of the book to want bad things inflicted on anyone in the human race?
I don't know.....maybe I am missing something here. Please. Weigh in.
