Thought I might as well put this somewhere, it's just the top ranked movie from each year on the various decade lists I've made. It comes out to being pretty well thought-out in the '20s, somewhat rote and ordinary in the classic Hollywood period, and maybe a little too eccentric during my lifetime (yes, I do think Brain Candy is brilliant). Also overwhelmingly comprised of American films, which may or may not change eventually. I've generally seen little to nothing from the current year so it won't be added until I've seen something that I rate four stars or higher.
Assuming I don't forget, I'll track changes in the comments.
