Well, one of the things that really bothers me about this series is the way the muggle world is depicted. Why should it be completely flat, colorless and unimaginative? Where are the good muggles? I'd like to see some normal people, please!

I do agree that the mimistry of magic seems completely hopeless. Just as you say, I can't begin to imagine what they will do about the dementors. Jodel, below, has a theory about that, and I hope she's right, but time will tell.
