In my opinion an interesting tool that could be used to sense the popularity of a character is a sourvey where to express the three (or at least the two) favorite characters.
Favorite -----> 3 points
Second favorite ------> 2 points
Third favorite ------> 1 point
With the possibility of repeating the same character.
I think that in such a way the scenario would be more precise and possibly significative different from which depicted from the simpler survey led some time ago.
