While the news sparked a lot of angry comments, there were a few fans of James O'Barr's graphic novel who wanted to see a new adaptation that might stay truer to the book. But earlier this summer, Comics2Film ran a rumor that Norrington wasn't going to use the character of Eric Draven, but was inventing a completely new character and storyline for his remake / reboot. Let me stress that little item hasn't been confirmed, but if it's true, it certainly raises the question of "Why bother?" O'Barr fans want their guiding crow and self-mutilation back.
At this point, all we know is that Norrington is aiming to make it "realistic, hard-edged and mysterious, almost documentary-style." Now that I've seen more of the graphic novel (thanks, Google Images), I can't think of a poorer approach to something so deliberately introspective. But who knows? If it's truly a whole new character who just happens to have a crow as a pal, the shaky-cam approach might work just fine.
