For some reason in the past few years, Hollywood movies have started giving away every plot point that's in their movies... IN THE GODDAMN TRAILERS. Every trailer has become a minefield; if you go too far into a trailer, you will see the entire movie in sequential order. This will include all the best plot twists, character arches, action sequences and surprises. You don't even have to see the movies anymore! They'll take you deeply through every emotion by the end of the 3 minutes... you'll feel excited, shocked, scared, sad, intrigued and by the end of it you'll have grown as a person... leaving you no urges to watch the actual movie.
A trailer should leave you with questions unanswered. Here's how a basic trailer works nowadays... first they suck you in in the first 5 seconds with something bold whether it's funny or dramatic or epic... which is totally fine. After that is where things go wrong... They start just sequentially going through the story from the beginning, developing the characters, explaining the conflict, showing the major scenes... and in every trailer, they will get to this intense point which is a HUGE PLOT point, that, if you were to watch the movie, would be the most suspenseful, interesting part... they build up the crescendo to this amazing point and you ask yourself... "Oh my god, what is going to happen??? I have to watch this movie!"
They just show what you happens. And all your excitement to watch the movie goes out the window because you now already know what happened. Depressing.
Older trailers used to give you a feeling. They would delve you into a world full of questions, and crazy scenes and crazy characters. You would get a very basic understanding of the characters and plot, but it would leave you wanting to know what happens.
I can't stand trailers nowadays. I literally worry every time I see every trailer that it's going to ruin the movie for me.
