I'm not saying that every person who admires an "unknown" director tries to come off superior, but it seems like some does. I refer to those who try to describe a movie with the most difficult words and technical terms they can come up with, e.g. bjornam. We are normal people, not movie critics. Because this is a message board where not only those in the business, but also just plain movie lovers write, maybe trying to keep it on a level that is understandable to the common man would be a good idea. And also, there are many here who does not have english as their mother tounge, like myself. 
My point about the list is that they don't say anything about the movie, they just show us what someones favourite movie is. Unless it's a well known movie, most people can't relate to it.
