A Midsummer Night's Dream
What is the magic used? Who uses it? What does it do?
What is the magic used? Who uses it? What does it do? How does it change the story? What would the story look like if it wasn't there? How does it move the plot forward? Is it used fairly and honestly? Is it used deceptively? Why is it used? Do the characters who use magic use it the same way, or do they use it for different reasons?
