We hear the complaint, "All the best parts were in the trailer!" with virtually every movie. The Social Network (i.e. the Facebook movie) tried to side step this by not actually showing any scenes from a movie that everyone knows the entire story of anyway. Instead, we hear it! It’s similar to how everyone complained that Zodiac had no resolution and was unfullfiling because we already know the ending. (There isn’t one.) It will be like that, only not a good movie.
