When JK Rowling killed off Hedwig for no reason.
What is the worst plot fail of a book or movie ever?
When we see Voldemort die, I mean it's set in real life people don't disintegrate what were they thinking!
I agree. I think it was so considerate of Voldemort to think of Harry's education though. He always waits until the end of the year before attacking. How nice of him!
