Possible Audience?

For our film I would suggest that the audience would be best suited to an almost horror like fanbase as there is a quick early murder that makes the viewer ask alot of questions. Because it would seem at first that there is no motive it makes them question why this man in particular would be targeted for a murder. There may be plans to place slight clues in the opening sequence where we realize something is wrong, but not too many as it is the opening of the film. Because of this I feel that the idea of a suspense, shock type of audience would be perfect for the audience.
