 Well, it's very difficult to define, and in the book I talk about how I think it's like film noir's definition, and that it's not necessarily a movie, it's an era. Because if you look at it, you have Sweet Feedback, which is technically an action movie slash drama. You have something like Blackula, which is a horror movie. You have Shaft, which is a neo-noir. So they cover so many different genres and sub-genres.
