What I love with JK Rowling, is that unlike remakes / cinema suites, each book is better than the last. Honestly, I expected at the turn after the first ... Well, she manages to keep quality of style and invention very surprising given the density of each Harry Potter. You and I know, if you're a fan, JK Rowling said he designed the seven books in the series as a whole from the start. Again, I was skeptical. But I have to go to the obvious: we can not catch her out of repetition. Ever feel that the situations we have are "fetched". Harry Potter (there) is as a single story, not a series of stories, a consistent and well paced block. For me, that's for sure, we have a work of literature (dare I write children's) that will last. Roll on the next one!
