Most Over-Rated Book

Everyone seems to love The Secret History by Donna Tartt, going on and on about its brilliance.  That was not my experience at all!  My blog entry from the spring sums up my feelings on this one perfectly.  I scored it a 1/5, while the average on Good Reads was 4.05.  How????  Also, how did this come from the same mind as The Gold Finch, which I really enjoyed.
