Comparison of Double Indemnity & Sin City

The are many differences between Sin City and Double Indemnity. One and I think most powerful difference is how women are treated in both movies. Sin City sees women as an sexual object, they are not respected, beaten by men and violent. In Double Indemnity they're dominating and seductive. They have power over the men. There are some characteristics in Sin City which have colors like red lipstick/dress/sky, blonde hair, yellow character. Whereas Double Indemnity is only in black and white.
Also the killing scenes are not graphically depicted, the killings are more subtle and implied, whereas in Sin City, brutal scenes of gore and violence are common place, due to it's comic book nature.
