I know many fans find Harry Potter and the Deathly Hallows disappointing. In one sense, I understand the feeling. The book differs drastically from its predecessors in both structure and tone. This is not simply “year seven” at boarding school. Harry, Ron, and Hermione have left Hogwarts to embark upon a more traditional epic fantasy quest to find magical artifacts.
Although Deathly Hallows probably could never have satisfied the fevered expectations of fans in 2007, the book does suffer from introducing too much plot too late in the series. Almost everything the heroes needed to do in order to defeat Voldemort they learn and accomplish in this book. It makes the book and the series as a whole feel unbalanced.
