JKR owes us revised editions of HP books!
A "slightly disgruntled fan" wrote an 80,000-word essay about everything he disliked in the books and wants JKR to rewrite HP in accordance with his wishes.

An excerpt from the essay:

Destiny Unfulfilled is designed to convince as many fans as possible that a revised edition is called for, so they can begin haranguing Ms. Rowling (politely and with restraint, of course). Never underestimate the power of peon pressure!
Creative writing students will likely also benefit from reading this book, as the careful analysis of the strengths and weaknesses of someone else's writing often helps us spot those same traits in our own work. Finally, students of composition can use this as an example of argumentative writing, as well as a jumping off point for school writing assignments, by either agreeing with or countering points made here-in.

Then he went to The Leaky Lounge to brag about his essay and to convince the posters here to beg JKR to revise the books.

An excerpt from his first post:

I do have an M.A. in English, but I feel my main qualifications for writing the book are that I'm a (slightly disgruntled) fan of the series, and I've put a lot of effort into analyzing the seven books. To be clear, this is not a religious diatribe, political axe-grinding, nor do I attempt to take Ms. Rowling to school on who should have fallen in love with whom in the series. (I am *not* a kook! Heh.) Rather, this is an examination of issues like the role of a protagonist, the writer's contract with her readers, characterization, shaggy dog resolutions, and so forth.

The critique makes claims such as that Harry fails to fulfill his role as a protagonist and, ultimately, ceases to be even a necessary character. Hermione could easily have made it through Book 7 without Harry and Ron tagging along after her.... That seems like a fairly major problem, when the title character turns out to be unnecessary.

I hope we can make enough noise to get Ms. Rowling's attention. We aren't asking for more books in the series, just that she fulfill the promises she made to us: that the books would star Harry as the hero and protagonist, that the books wouldn't be episodic, and so forth.
