Query: Harry Plodder

The long awaited 5th entry in the Harry Potter series is a monumental disappointment. In 870 pages, almost nothing of substance happens. And most of what we read is not connected in any way to anything else. We plod through scenes of Harry on a date, the giant Hagrid hides in the forest, etc. And there is nothing in this book that contributes to the overall story of the return of Voldemort. We knew he was back at the end of Goblet of Fire, and by the end of Order of the Phoenix, well, he's basically still just back. Except that he's spent the entire book more or less in hiding while his Death Eater cronies try and get their hands on "the prophecy", which tells us no more than we already knew about the characters. And yes, the end of the book leaves us on the dawn of a new wizard war, but we figured that was going to happen at the end of book 4.Skip this installation, and wait for number 6. You'll have missed nothing but a lot of Harry yelling at his friends in bold type.
