It's a black comedy...
As the editor on this movie, I feel inclined to say that most people watching this film have been misled.
This was written, directed, and edited as a black comedy. If you enjoy the campy "Slither" then you will understand what I mean. There are quite a few "slasher" elements, but it only goes so far. If you want to be entertained then I feel Brutal does its job. Sit back, relax, and have fun. Don't take it too seriously. If you feel the clues are too obvious it's because they ARE. The sheriff and deputy are incompetent-- and that is what makes it funny. We took the stereotypes of the genre, and put them in the forefront...Think of the film "Scream" but not so slapstick. Don't be afraid to laugh.
