Daybreakers trailer is crazy confusing.

I like dystopian future movies. You know, the human race is in danger, people fighting for their life when its obvious they won't survive. Those movies are great. I thought this movie was one of those. The first 23 seconds of this trailer make it look like one of those. But at second 24 some creepy guy screams "TO FARM THEM FOR BLOOD!" WHAT?! Way to flip the script television commercial, I have just lost all interest in this movie.
