Frank Miller adapting Will Eisner makes about as much sense as Sam Peckinpah adapting Jeeves and Wooster.
When Quentin Tarantino made Jackie Brown from Elmore Leonard's Rum Punch, people were all "dazzled" by how brilliant it was, this fusing of two great dialogue masters. Personally, I found that Tarantino's choices, starting with moving the story out of Miami and working right on through the list, did nothing more than systematically eliminate everything that made the book charming and great. In the end, what you had was something that was Tarantino's flesh and fetishes hung over the barest mention of Leonard's skeleton.
I fully expect that's what we're going to have with this Spirit movie. Frank Miller is possibly the least qualified person to adapt Eisner (personally, I think Kevin Smith would do a better job), and I'm glad Will's not around to see this.
He who steps on others to reach the top has good balance.
