I really liked the storyline and the Hammet-esque plot turns of this one, but why did there have to be robots? In my opinion, the story would have worked just as well with normal humans in all the robot roles. The world seemed just the same as the normal noir world of the 30s but with robots added in. I'd think that more things would be different in the world as a result of the existence of robots.
In Blade Runner, also a noir with robots, the existence of robots was integral to the plot. I didn't feel that way with Chrome Noir.
