I think even more so than the Lord of the Rings series, Harry Potter on the big screen beautifully emulates the writing of JK Rowling. I am impressed how as you sit in the theatre watching these films you become completely immersed in the world. Even though the movie appeals a lot to the under 18 crowd, the themes in the film are dark and deep and this is just one of the things that makes them so good. As an NIH researcher, I think I would have to dress up as Harry because there is something geeky about him that I share.
