I think the Spawn movie was great when it originally came out. I can still remember all of the hype over the CG work that was done on his cape when he fell through the skylight. At the time, it was cutting edge.
I really do wish Todd would go back and create a dark and gritty version. Spawn has been one of my favorite characters for YEARS. In fact, it was one of the first comics that I ever picked up. Started collecting at issue 9, I believe. And as for the animated series, it was nothing short of phenomenal. It was what the movie should have been but really couldn't. And yes to the idea of giving Spawn the Darth Vader treatment (faceless person in suit, good voiceover...Keith David. )
Come on, Todd...your loyal Spawn fans await!
