In my opinion, the fifth of the worst one out of the brilliant series. There hasn't been many important aspect discovered in this book-besides the very imporant prophecy about Harry and Voldemort, and Sirius Black's death (but I think he will play an important part in the upcoming book). Besides this, throughout the book, Harry Potter has been an arrogant, blustering young boy-extremely negatively affected by his ongoing puberty and misunderstood throughout the novel.
