Sin City-
Just rented and watched it three times. I'm curious to see what the graphic novel looks like that it was based on. A good movie to watch more than once. Some things were left a bit unexplained, though, in my opinion. Like the relationship between Clive Owen's character and the head hooker. Could it be that it was explained more fully in the novel?
The graphic novels look pretty much exactly like the movie, probably about 1/3 of the novel frames are in the movie in as exact a replica as digitally possible. The movie is really 3 of the 7 graphic novels (1 of the novels though is actually just a collection of smaller stories). I don't think that relationship is more fully explained, Sin City is really about mood and tempo, relationships are only described as deeply as absolutely necessary.
