Mr. Byrne, I would love to see you go in that direction. I would love to see anything (CITIZEN ZERO, NEXT MEN, YGG, historical stories, sci-fi stories, etc.) done in this format. As much as I love your super-hero comics (BATMAN/CAPTAIN AMERICA and the first GENERATIONS are my absolute favorites of yours), it would be really cool to see such an interesting variety of projects from you. Bring it on!

Wow, how the heck have I managed to miss this thread for something like a week???

JB - you've got some great ideas going there that would really suit the more novelised (without previous serialisation*) approach. The end of Next Men sounds great in just about any format (goes without saying really), but all other suggestions, Elizabeth in space and Citizen Zero in particular sounds awesome.

I'd also like to say that it ought to be high time soon for a JB adaptation of City at World's End. Really, truly... high time!

*  I always find it worthwhile to remember that  most of the early modern novels were published in a serialised format before being bound as books (Dickens being a major novelist working in this manner of course).
As such, I've always found the term graphic novel a bit flawed in its usages in two ways.
1) neither the medium of comics nor any TPB collection of comics material equals, to my mind, a graphic novel, as there has to be something novelistic about the collection (by which I'd argue that some TPBs collect material that effectively do function in such a novelistic manner while other most certainly do not).
2) Many (early) graphic novels, e.g. Marvel's graphic novel series from the 80s, strikes me also as less novelistic, in terms of scope. The length of something like God Loves, Man Kills would perhaps merit the literary term novella, but some of the even shorter ones makes me more think of short stories proper. I can sympathise with the differing effect of publishing in a different format, especially at the time, but there is something disingenious about using the established term novel in graphic novel as something more of a synonym for book.
The novel as a literary genre after all comes with certain "formal" definitions, and a graphic novel should to my mind have some correlation to those definitions (although adapted for the comics medium) if the term is to be useful and not just a fancy schmancy way of saying "comics" for people who don't read "comics".
