PROBLEM: Pure Shlock . I generally don't enjoy reading books with teenaged legs and sunflowers on the cover.  I often read on the subway, and it can be a bit embarassing.  If I chose to weather the pornographic implications of such cover art, I expect to be rewarded for my sacrifice--with, say--A GOOD BOOK.  I'd even settle for full characters who change and grow.  I'd settle for dialogue that occasionally rose above tediousness and pointlessness--perhaps dialogue that, in fact, advanced the plot or advanced character development.  If I am going to sit on the L train with a book that slightly resembles a Baby-Sitters Club Epic, I would like for that book to be enriching/rewarding/entertaining/redeeming.  Why is this book 400 pages long??!!!!  Nothing happens.  The family has the same conversations over and over again, and nothing ever changes, and the father character is so irresponsibly designed that his dialogue is virtually identical to that of her 31-year-old boyfriend, Oliver.  No one comes alive, except maybe the mother.  I found almost nothing to hold on to in the entire novel.  The opening line was intriguing.  From there on out, it becomes progressively worse.  I felt only for one person: the mother.  Because she sat in the background, hands folded meekly, kind of depressed and annoyed, for the entire book.  Which was a lot like how RR made me feel, too

SOLUTION: NEG

PROBLEM: An idiotic or deliberately misleading book - take your pick . I read this book in order to see if it would change my opinion about the status of social security. It does not. In fact, it glosses over the key, overriding issue: that the so-called "social security trust fund" does not in fact exist. The claim that huge surpluses are being mounted is meaningless when all that really exists is an IOU that the government writes to itself.     The book spends all of one paragraph (see page 28) on this critical issue, suggesting that the reader imagine that the fund is invested in private stocks and bonds, rather than government bonds, and concluding, "It is difficult to see why the composition of the trust fund's portfolio should make any difference." I just about threw the book across the room at that point! In other words, the authors see no difference between a fund backed by real assets that can simply be sold and a fund that will require raising taxes or additional borrowing on an enormous scale

SOLUTION: NEG

PROBLEM: In My Trashcan . This book is awful.  What a disappointment after such great success with Theodore Roosevelt.  I forced myself through half this book straining to distinguish reality from the fiction and fantasy that Morris interjects willy-nilly throughout.  What a chore, what a bore, what a waste.  This went in the trash can rather then the bookshelf to insure no one else might pick it up and waste as much time as I did on it.

SOLUTION:
NEG
