With the characters that are actually awesome that get unjustly labeled Canon Sues, yeah, I agree with you, but I'm thinking of the (rarer) ones that feel like they have talent layered upon talent just for the sake of it, to the point where it becomes absurd. As a feminist I can celebrate that kind of empowerment, but as a reader it's just dull to me and highlights a lack of skill in characterization.

Whereas the "not that special but is the right one for the job" type of character, yeah, is revolving around the romance, but are less painful for me to read because they aren't a bundle of talents and angst-causing-circumstances. I think they're still called Sues because they're purpose-written rather than organic and still tend to lack flaws, but they don't always tend to go along with bland writing.
