World_Film_Institute's "WFI ANNOUNCES 100 GREATEST MOVIES"

Lists of Bests will never allow you to finish this list (if you’ve seen all of them, it will show as 99%; if you’ve seen 88 of them, it will show you as 87% completed, etc.). I believe it is like this for everyone.

As this is a closed list, I suggest that the original poster replace each film one at a time until the bug is found.
