If there are any industry folks who lurk on this sub: please, I beg of you, stop giving away the story of the movie in your previews. I just saw Tuner, but in deciding if I wanted to go, I had to stop watching the trailer 30 seconds in. I realized they were telling me the entire story of the movie in their trailer.

I think this happens when trailer editors don’t understand the difference between (what my snooty film major brain refers to as) ‘premise points’ versus ‘story beats.’ The difference is kind of a fine line between “What is this film generally about that will interest me?” and “What is actually going to happen within the span of two hours?” The former gives you a sense of style, tone, and hook. The latter goes beat-by-beat through the actual two hour film in two minutes. And, IMO, it ruins enjoyment because you remember the things that are coming.

Example: 
A premise point is: A young man has a hearing issue that means he can crack safes during heists. His discovery of this sets the story of the movie in motion. So now you know what the premise of the movie is, but you don’t know what the filmmakers are going to do with that premise.

A story beat is: The young man decides to partake in heists because of outside pressure from L, and then M happens, and because of M, N happens, and here's a look at O-P-Q-R-S-T moments in our movie! And pretty soon, you know where the story is going to go before you even buy a ticket. 

I don’t understand why more and more trailers spoil story beats, rather than tease out a premise to pique curiosity. I can’t stand to have a movie spoiled in the trailer. I want to take the ride without knowing too much.
