Topic of my choice

For my final project I'm thinking of doing something with Harry Potter.  I've already read all 7 books in the series and watched all 5 movies.  One possible aspect of the series that I can do my project on is the cultural phenomenon that the series has had and still has on children, teens and even adults.  Some possible sources that I can use are the movies based on the books and analyze how they attract younger generations.  Another possible source that I already have is the book Muggles and Magic: An Unofficial Guide to J.K. Rowling and the Harry Potter Phenomenon.
