There's going to be a lot of death in this movie so the slasher element will always come up but I don't think the Strause Bros are trying to make a slasher film. I guess it just depends on the person's perception of how they view the film.
I don't look at as a slasher film, but more Sci-Fi/horror/action film. A good mixture of the elements from the first Predator and Alien/Aliens. But this movie I know will not be as good as those films. No way in hell.
