I've been a BIG fan of the comic since it started waaaay back in 'Dark Horse Presents' and have all sorts of cool Sin City stuff around my house (prints, Zippos, a mirror, etc) so you could say I'm a geek for it. I always hate looking forward to movies as they tend to disappoint me- a symptom of getting older I guess, lol- but I will be there tomorrow to see it and from everything I've seen it looks awesome!
I'm a big fan of Robert Rodriguez's work and of almost all the people involved, so at least I feel the heart of the film will be in the right place.... pulsing in someone's bloody hand after having been yanked from their chest...
