What's the Author's Motivation?

I like movies, but I'm typically disappointed with movie trailers.   Quite often they reveal too much of the film's plot, or they choose unique moments that give me a misleading sense of what the full feature will be like.

I suspect the problem is... the folks who make the movie trailers don't have the same motivation I do. Their primary objective is to get me to start watching their movie.  My motivation is to have a great movie-watching experience from start to finish.

It's important to pay attention to the source of the content you consume, and the motivation the authors have for producing it. Do you read articles, books, and essays written by people who are paid to attract eyeballs? or by people who are committed to the long-term hard work of delivering valuable insights and perspectives?  These two objectives are not mutually exclusive, but one is always primary.  Choose wisely!

In case you're wondering - my current criteria for deciding whether to watch a film is: watch the first 30 seconds of a trailer to see the ambiance and tone. Then look to see if the audience ratings are positive (I find the critics' ratings do not correlate with my preferences).
