The least successful Harry Potter book
4 stars
This is, to my taste, the least successful Harry Potter book. It just meanders from scene to scene, dwelling on characters' backgrounds, and not achieving very much all the while. Of course, it's still entertaining to a large extent and manages very well to build upon a sense of urgency that will carry through the remaining two books.
I think Rowling went a little over the top with the Umbridge character, though: she is just so hateable that one is constantly grinding one's teeth while reading about her rise to power, and her fate (in this book) is so far from satisfying that a lot of bad feelings towards her remain well after the end.
