I've just never found a trailer to be an accurate representation of a movie's themes, story, characters, etc. I prefer to judge a movie by the movie, not the trailer. A trailer is less than 1% of the movie so who knows, the movie might be great or it might be crap but I won't judge it on a trailer unless it says something deliberately false, misleading or insensitive/insulting.
The problem with these kind of movies is that they usually focus in on one or a few individuals in order to the story. Anyway, I'll be more interested in whether it is a good movie.
