What'll happen if you end up hating the genre, like the podcast's Marx Brothers Marathon? Are you more likely to severely trim your list down to the Essentials or abandon the project?
I don't foresee this happening, especially since by "marathon" I just mean that I will eventually work through the list, so it won't be an intensive project, or at least not too intensive. If I do have that reaction, I would tend to think I would trim the list to Essentials rather than abandon the project. I don't like abandoning things, or else a few of my other marathons would be lying in the boneyard already.
This is cool! Shows the different directors who have lots of titles, but I like finding the words in titles, and how prominent they are. Like "west", "man", "river", "bad", "seven", "gun", and "wagon".
