What are the moments in movies, like plot twists that you didn't expect?

mine are:

-The Dark Knight - Rachel's Death

I so didn't think of that, I was sure such an important character and it's Batman, so I was shocked

-Gladiator - Family's Death

I was sure that guy would make it in time, I dodn't believe he would be too late

Kick Ass, when Dave came flying in with a fucking jet-pack. The comic was so awesome, tragic, and realistic with some truly human moments and some scary surprises. The movie bastardized most of these moments........and then, it totally went batshit crazy. I was surprised how Hollywood fucked up a movie that could have been made shot for shot like the comic, with the budget of a TV show.

Sixth Sense, when you find out Bruce Willis was dead all along. I was shocked that so many people didn't figure that shit out at the very beginning of that god awful movie.

the crying game, what an unpleasnt surprise

Every episodes of LOST.

The Others
when nicole kidman and children finally realize theyre dead at the end of the movie
simply surprising

Night of the Living Dead
Ben, the last person left alive in the house, manages to survive by locking himself in the basement after the zombies break in. The cavalry arrives the next morning in the form of a bunch of good ol' boys shootin' zombies real good. Unfortunately for Ben, as he runs upstairs to greet the rescuers, they mistake him for a zombie and put a bullet in his head. -.-

I think that might have been a social critique of some sort.  The ben guy was the first black guy in american movies to star as the hero of the show but gets shot in the end.  So mabey george romero and the writer thought that black people have a long way to go or something

Luke, I AM YOUR FATHER

Stella getting her grove back, I didn't see that coming at all!
