It was refreshing to read a different take on Rowling, such that we are sure that the secretly reverse British invasion is not immune to a knock on the door.
Editing the sixth book poorly though is really overdoing modesty. It isn’t sure that the sixth book could actually be made into a film. How would they get to the end of the series? Perhaps revising [Half-Blood Prince] before writing the script would ensure that the whole series of films is satisfying to children really.
