You know, I think I've seen that film...
Then again, if you were going to do the same thing with my preferred genre,* the archetypal trailer would just feature a lot of explosions, actresses in tight body suits, and excessively anthropomorphic aliens,** so I suppose I ought not throw too many stones.
* That is to say, sci-fi. And preferrably not sci-fi that is trying to be "meaningful" because, as a general rule, hollywood sucks at grasping what is meaningful or interesting in sci-fi.
** Or, if you're really lucky, a merger of several of these categories.
