What I aim to do, if possible, is set up several lists that rank the movies according to a criteria. An example would be a list of the "AFI 20 best drama films ever". I can create a tagged list of movies and call it "AFI 20 Bes..." but, I can not see away of ranking the films. I've looked at categories, tags, genres, reports etc to no avail, it seems ranking is impossible. And then there's the problem of a movie appearing in several different ranked lists? I have spent way too much time searching for the answer so hope someone can help me out before I go cross-eyed.

one idea-  may be on top of the tagged titles for each category,  is for either for AFI titles is to use their ranking  ( i.e.) #1  is (drama) Citizen Kane  or  (comedy) Some like it Hot etc etc ..  you could edit the listed title under 'sort Title putting a 1, or 2 , 3 etc will put those tagged titles in the order you perfer ...
