Is the title appropriate to the story?

Well, first of all it doesn't necessarily have to.

For example the the title of the novel Frankenstein gives no hint whatsoever about the theme of the story.

The subtitle 'The Modern Prometheus' however says a lot about the theme - that 'the uncommon man' will suffer for his doings. In this case referencing the mythical Prometheus we immediately know a lot about the theme might involve.

In other cases the title may say things about the theme directly. The title to the novel 'Sense and Sensibility' suggests that the story will compare and contrast the virtues of each trait ----- and it does.
