IF..
you had used the same blood style as the last kill..this movie would have been fucking awsome. What do i mean, you ask? the last kill, he blows the guys head off- sending the head flying across the room and tons of blood splatter everywhere. Also the puddles at the end looked nice.
But why didnt anyone fight back? They just sorta..stood there and took it (kinda like that kid who accused M. Jackson of molesting him, huh?)
