I'm not sure how much bad films from directors weighed in to my calculation compared to quantity of good films. Sure, if two different directors had two great films (M. Night and John Cameron Mitchell for example) but one had a number of bad films while the other had none (well, no other films period), the latter will get the vote. But if it is someone like Sodeberg who had say five films that I liked, even with five I didn't like, he'll get favored over the one with the better "net".
