I didn't see anyone else mention it, but the scene in King Kong where one of the guys is eaten alive by four or five giant worms, each one starting from a different limb (the last one swallowing his fucking head).
Doesn't matter that they were setting him up for you to root for him to die, it's still way too much for me.
Oh yeah. Creators did a great job at making that as dirty and greesy as possible for whatever reason. I don't understand why, but there was much effort to drop that bomb onto the viewer out of nowhere.
