I am a HUGE Harry Potter fan, so I fail to see the point of changing the written story to any degree. Leaving some things out of the movies may be understandable but DO NOT CHANGE THE STORY!!!!!!! I am speaking namely of Dumbledore's death scene. That is a pretty HUGE change to the story! Can we get a re-do please, maybe get a different writer?
I would have much rather them leave out the silly Burrow scene that was not in the book and the silly Bellatrix in the great hall scene that was contrived by the writer. I would have much rather seen the fight at the castle and a lot more about Harry and Ginny, and quidditch, and the list goes on and on.
