Well, I managed to fix half of the issue, but can't figure out the formula for the rest. So films that weren't in the 2018 list will display as "new" as their rank instead of "--", in red if they were in the 2015 list and in green if they are showing up for the first time in the 2020 list.
Here are the ten runners-up (without pics)

And I just realized that AKAs aren't showing up for the non-English titles. Hmm, I'll have to fix that too (added the ones in here manually for now). Looks like I never added them to my results spreadsheet in the first place. Weird.
