Batman Returns/Nightmare Fuel


 * With surprisingly gross behavior from the Penguin (i.e. biting a man's nose and his death scene where carcinogens pour from his mouth). There's also Selina's breakdown and Max Shreck's demise.
 * The Ice Princess falling to her death... especially since we see her screaming all the way down and hitting the ground. Even Die Hard didn't do that, and that was an R-rated movie!
 * See Fridge Horror where it is implied that the Penguin has been murdering children his entire life.
