The way I think of characters is different for different media (books, comics, TV, movies, etc.).
The way I think of characters has probably been affected by role-playing games either in person or on the computer.
One good character can carry an otherwise-worthless work for me.
One bad character can ruin an otherwise-fine work for me.
I have modeled characters (in fiction, gaming, etc.) after people I know in many details.
I would be creeped out if someone modeled a character after me in many details.
I would be flattered if someone modeled a character after me in many details.
I have to have a single favorite character in a work of fiction if I'm going to enjoy that work.
I have one favorite character of all time across all media.
I have one favorite character of all time in at least one medium.
Were you not listening? When I said the part about not caring about characters?
