Fridge Horror: At one point in A Million Suns, a group of people on Godspeed speculate that someone else could do a better job running things than Elder, giving serious thought to kicking him out of power in favor of another person. One of the names thrown out as a potential candidate? Luther. Who stirs up riots just because he can, who has raped women and tried to rape Amy, and who was very good at hiding his behavior from the public in general. Imagine what things would have been like if he had been put in charge...
Ho Yay: "I Want You (She's So Heavy)" might just be the most homoerotic scene in any movie ever. The army recruiters get awfully handsy while singing a song originally about sexual obsession and lust to a bunch of half-naked young men, as Prudence gayngstfully sings about her own obsession with Sadie.
The little boy's funeral. Buckets. All of "Let It Be".
Uncanny Valley: The recruiting officers in the "She's So Heavy" sequence; they look human, but their identical uniforms and stiff, precise movements are complemented by the fact that they all have unnaturally massive Lantern Jaws of Justice that make them all appear like identical living mannequins.
The Woobie: Everyone, but special mention goes to Prudence.
