Sorting option 2: Unique star distributions. Films that divide the most (and vice versa).
I've often thought how wonderful it would be to especially search for controversial films by programming an option to search for flicks that have the most widely distributed star ratings.
We’ll think about that. We current produce a “Most Divisive” list using this technique at the end of each year (see: http://letterboxd.com/2015/ for example).
