Got your attention with that rather dubious thread title ! Well it's the unexpected out of charector moments that can shock the audience on first watch for example. Quint , and his demise that I didn't expect on my first watch many moons ago. Lukes daddy in Star Wars , but what I'm getting at is the like of the assassination of Axel Foley mate in Beverly Hills Cop that seems out of charector with the rest of the film. Drive for example came out of the blue with the verosity of the lift scene. Just some examples and they do not have to shock for shock value, just unexpected moments that shocked you at the time.
