Does a movie's presence in one or more of these categories mean the film is racist? Not necessarily; it could just mean the screenwriter or director is being lazy and unimaginative, resorting to easy shorthand instead of bothering to create well-rounded and fully human characters or narratives that transcend clich. It's important, however, for filmmakers to realize that these kinds of stories and characters have a long history in Hollywood, that audiences with an awareness of film history recognize the tainted past that informs such imagery, and that these are therefore traps that vigilant filmmakers will take care to avoid.
