Y'know, I never though of Omelas stories being cliché, but you're right--I have seen LOTS of stories with that exact same twist, including at least one Doctor Who episode. Which is weird, considering I haven't read the original. I should do that. . .

Between that and "Lips Like Sugar"--working-class-vampires, queer rep, AND an Echo and the Bunnymen reference, yes please!--I clearly need to familiarize myself with Cynthia Gómez!
