Running away from the footnotes? Heh, when I picked up the book, I looked at the footnotes and went, "Interesting, never seen footnotes in a children's book before..." and then I started to laugh. Quite loudly.
As for graphic novels, well...for some stories it is the perfect medium, as the book format was the perfect medium for the Bartimaeus Trilogy. However, while we may lose many of the better jokes, we may gain a new dimension of atmosphere and character. Sullivan is a very good artist.
All the same, it boils down to how they deal with the story...hopefully Mr. Stroud does have a hand in the scripts and such for it.
