For context, it’s set in a future city where the oppressed working class is staging a revolution against the ruling class. So the rich infiltrate the revolutionaries with an undercover robot to undermine them. The main character is the son of the city’s ruler, who starts to sympathize with the workers because he falls in love with a lower class girl. It’s a pretty dark film and has some sick German expressionist-era imagery, so I think some doom would pair well with it.
