The Fans and the Films

I would love to have your input re reading the Harry Potter books and viewing the films. This relates to Chapter 12 of my recent book, On the Trail of Harry Potter. Since I was invited to speak on the subject at the Orlando annual convention, at the Potterwatch convention in North Carolina
and elsewhere, it would be very helpful to know what others are thinking. For example:
1. Do you personally think the films enhance your reading experience? If so, in what ways?
2. Did you feel gratified or disappointed in the way any or all films portrayed the characters, the plot or the meaning of the books?
3. Any other reactions to share?

Thank you so much!
