Shipping aside, I really enjoyed book 6 for the most part.
Book 7 though, disapointed me a bit on some accounts but I don't really care because the series as a whole is just amazing.
I always noticed that teensy bit of H/Hr potential while reading the book, and it still boggles my mind why JKR still prefered the OBHWF concept. But better keep H/Hr beautiful the way they are and untouched than two sloppy kiddie romances that have no potential for a longlasting relationship.
