Rape is no more a cheap storytelling tactic than murder. Notice, I did not say killing, I said murder.
Movies will show villains kill the defenseless to set the tone that they are bad. Stories use rape to the same end. Ultimately, murder is as bad or worse than rape. It may seem less villainous when seen on-screen, but it is still a vicious crime used as a storytelling shortcut.
Should film and other stories use more subtlety instead of these shortcuts? I don't know. I suspect the answer to that varies with what the person creating the story wants to do with it. I've heard good things about those books about a woman with a tattoo though, and I've also heard some pretty rapey things about it, so its not as if it never works to use as a plot device.
