"Because the true perfection of a practical occupation consists not only in knowing the actual performance of the occupation but also in its explanation, why the work is done a in a particular way, and because the art of calculating is a practical occupation, it is clear that it is pertinent to concern oneself with the theory."

I know, that trends and all of those things and formulae that calculate what audiences want to see and what audiences don't want to see and various other demographic demarcations are the eccentric and ludicrous prerogative of Hollywood studios. But out there in the real world - by which I mean the rest of the world where we make truthful organic films, independent films unimpeded by interference - it's not about all those sort of calculating what is commercial. It's about wanting to say things and saying them in a way that will get through to people.
