I'm a big fan of the Harry Potter books and movies. I think the actors did a wonderful job in the Half Blood Prince. I especially like who they picked to play Slughorn. But the changes to the story line, I feel, were unacceptable. I understand they need to edit the storyline down because of time constraints but they completely added scenes that were not in the book. Why not leave that nonsense out and put something in that they actually cut from the book?!?!? Anyway, I waiting in line for six hours Tuesday night for the midnight showing and now wish I had those 6 hours of my life back. If you must see it, please consider waiting a couple weeks until the hype dies down. You'll thank me if you do.
