Warning: #&@*$! Spoilers

Marketing people, particularly marketing people who work for big corporations, don't care about you. These are not good people. Now, don't get me wrong, I'm sure individually they don't beat their dogs or anything. You could probably have a civil conversation with one. But get them in a room together, and they are evil. When studio marketing jockeys gather in a meeting to discuss how to promote a movie, they don't care whether you like the movie or not. If they give away the ending, if they give away a pivotal plot point that actually ruins the movie for you, they do not care. Period. Their job isn't to get you to enjoy the movie.

Thus, marketers and creators -- who should be on the same side -- are actually working at cross purposes. How screwed up is that? As a writer or a director, you strive for a wonderful story, with dramatic tension and interesting twists. Specifically in a movie (as opposed to a book), you try to create moments when the viewer is looking at the screen and just says, "wow."

Marketers get hold of these moments, and they say, "wow," too. But then they put those moments in the trailer and the ads.

Imagine experiencing one of these movie moments for the first time without some marketing "genius" spoiling the secret first (to avoid terrible spoilers of my own, I'll pick older, widely seen movies):

* In Dark City, when we learn the weird bald guys are actually aliens and can reshape the city.
* In The Abyss, when we discover that there are aliens under the water.
* In The Matrix, when we learn what the Matrix really is.
* In T2, when it turns out Arnold isn't there to kill John Connor, but to save him.

Now, I chose these movies because I saw each and every one of them on opening night. These moments weren't ruined for me by people who saw the movie before me. They were ruined by marketers. And I'll never get them back.
