Con men are more appealing than run-of-the-mill villains, who want to take your money because they are stronger or more dangerous than you are. Con men want to take it because they're smarter than you are. And there is hardly ever a con man who isn't likable, because, after all, if he can't win your confidence, how can he take your money? Movies about con men are seductive because the audience is on both sides of the moral issues: We want to see justice done, of course, but at the same time we're intrigued by the audacity of this character who is trying to out-think his opposition.
